Summary of article: in an uncertain job market, some young people are going into blue collar trades. Others are starting startups. Others are powering through. Journalist says some words about "AI" being the cause of all this uncertainty.
Not sure how it works in the US, but in some parts of Europe, blue collar trades are currently much better, for several reasons:
- Price of housing and associated maintenance keeps rising, and so do small jobs like fixing plumbing, gardening, etc;
- You can easily avoid paying VAT if you know how to, so that's a 20% increase, or even more, if you can benefit from social services (e.g. since you don't earn a lot, you pay less for several services);
- Doing the fixes yourself saves lots of money;
- Avoids several burn out and mental health issues related to stress such as academia, bullshit jobs, etc;
- No need to spend years in school, so you can save money earlier and invest it.
One disadvantage is that the barrier to entry is somewhat low; but the PhD students also have to compete with cheap international labor, so in the end, someone 25 years old that just left grad school is happy to earn, say, 2000€, while someone in the trades can easily make 200€/day with just one appointment.
So, if you're physically fit for blue collar work, there are currently few reasons not do it.
Is it actually true that the savings on home maintenance and social services offsets the higher salaries of white collar work? That's kind of crazy if it's true.
In the US, you can make pretty good money in the trades, but generally, there are many caveats - you have to be your own boss, preferably with a few employees; you pay your own benefits; you don't get any paid leave; and depending on the trade, you could be physically worn out before minimum retirement age (65 in the US to get health coverage as a retiree).
In Germany I'd say you still make more with white collar, if you have a job. The problem for Gen Z though, is that they aren't hiring for junior positions.
Still if you go blue collar you have to build your own business.
This could be said of literally anywhere except a ghost town, and it's only true in a very narrow sense. The problem is not housing supply. It's zoning, which is a political decision.
Might be surprising but I am kinda willing to believe it. Since we bought our house, we had quite a bit of work done by professionals. But whenever I can I do things myself.
Like I had multiple companies quote me $300-500 based on the job for things that take me maybe 2-3 hours total to do, including learning about it (will be faster next time), getting the materials, and doing the job.
When you have a few of these a months they add up. It is usually nothing for a month and then 4-5 things to fix/improve the next
Yes. It’s relatively straightforward to work on a fixer upper house during which time you are drawing no salary relative to that, and then you can turn around and sell it (or just enjoy being in a nice house which otherwise would have cost hundreds of thousands).
From what I see on the other side of the ocean, the same applies to Europe, at least to Italy. Add to the list: wake up early, drive to customers all the day long, learn to always smile and be kind to customers even when they don't deserve it.
> Is it actually true that the savings on home maintenance and social services offsets the higher salaries of white collar work? That's kind of crazy if it's true.
$10-20k of home improvement work adds considerable value for reselling, and you're only on the hook for raw materials -- you've already got the tools and skills and time
one of the wealthiest dudes I know is a carpenter who loves workin wood. his free time is spent making cabinets and furnature and blasting obscure music
You would be highly advised to learn how to do basic plumbing, electrical, and renovation tasks yourself in the US as well. The cost savings is enormous. Finding a quality contractor, in addition to being expensive, can also be very hard - there's plenty of people doing plumbing or electrical who might be licensed and everything but are grossly incompetent or never finish jobs.
A lot of stuff in the US is absurdly easy, as well. For example, in my area, pretty much all plumbing is PVC or PEX. Anyone on HN can learn very quickly how to work with this stuff and it's very cheap. There are very few repairs, for example, you could ever need to do that would cost more than having a plumber just show up and look at it - even accounting for buying tools.
Yea, at least over here in Finland many university degree programmers are hardly worth it, even though there are no tuition fees. A plumber or electrician can easily earn more than a researcher with PhD, with much shorter studies, better job security and more options for starting a business.
I know lots of people with master's degrees who have started studying something practical after graduation, as they were unable to find any job with their degree. Of course the general economic situation (highest unemployment in the EU) is having an impact on everyone, but it's hitting those with higher education particularly badly this time.
Yep. The ability to work without paying taxes in this profession is of enormous value. It keeps prices lower for the consumer, and income higher for the handyman.
I seen many handymen with the latest and greatest luxury cars, and the demand is endless.
On the other side, it seems technologists salaries are stagnating, and the new guys on the market get lower and lower salaries, so it does indeed seem as if the best and quickest way to retiring early is the handyman approach coupled with a high level of non-taxes work.
A Soviet engineer needs some plumbing done in his apartment, and calls for a plumber. The plumber arrives, does his thing, and hands over the bill.
The engineer is shocked. -'What, this is like a quarter of what I make in a month - for half an hour's work???'
Plumber shrugs. -'Well, why don't you come join us? Easy work, well paid, no responsibility - just remember to keep mum about your degree, as we're not supposed to hire academics.'
Our engineer contemplates this for a while, applies for a job as a plumber - and gets it.
All is well, good money, no responsibilites - until management requires that they take evening school classes to gain new skills and thus better build socialism. So, grudgingly, our engineer enrolls in a math class and, upon arriving, finds that the teacher wants to establish what the plumbers already know.
-'You over there - could you please come to the blackboard and show us the formula for the area of a circle?' he asks our engineer.
Standing at the blackboard, he suddenly realizes he can't for the life of him remember the formula; while a bit rusty, he soon figures out how to reason it out - furiously writing out integrals on the blackboard, only to find the area of a circle is -(pi)*r^2.
Minus? How did a negative enter into it, he thinks, going over his calculations once again. No, still gets the same result. Sweat building, he turns away from the blackboard for a moment, turning to the other plumbers watching.
As in one voice, they all whisper -'Comrade, you must switch the limits to the integral!'
Here the barriers to entry are high imo but artificial, you need to complete an apprenticeship paid for through opportunity cost of lower wages and less working freedom for a few years.
> - You can easily avoid paying VAT if you know how to, so that's a 20% increase
You mean by how VAT is not paid on materials a company is going to use (at least that's the case here in France, no idea what the rest of the UE does it). Or by doing undeclared work?
How will people be able to afford to pay for blue collar labor though, when AI will potentially have decimated all white collar and many blue collar jobs; that's what I worry about.
For example, if someone decides to stop being a software engineer and become an automobile mechanic, but few people can afford an automobile; they demand for their services will also greatly diminish.
I recently had a chat with a young person who'd recently graduated with a degree in marketing, found the work entailed unsatisfying, and left that to become an apprentice electrician.
He said that with the tariffs situation work had severely dried up and jobs were tight. This was in the PDX metro area. It makes one wonder what is really safe...
So a lot of people might lose their jobs because of AI, right? But the same amount of economic output, probably more, will be produced because of AI. By whom will that output then be consumed? If people don't have jobs they don't have money to buy and therefore ... prices will have to come down!
Society as a whole will be better off because there is more output, better quality output. Then it's for us to vote in a government that shares the fruits of AI with everybody, by way of progressive taxation. Government, use the taxes you collect to give us free food. We don't need 5-star restaurants, just healthy food. We can do this, in a democracy.
I don’t think kids should be insulating from AI. The examples in this article suggest for example that some people are dropping out of college and going into trade schools. I get that society needs electricians and construction workers and new software graduates are finding it difficult to get jobs. But having had a moderately successful career building software, I tend to think there is a lot of scope for the $40 trillion white collar economy to be disrupted (re-imagined/made more efficient), so still see potential for software engineering demand to stay high over the next decade as the true ramifications of AI plays out. Am I biased/coping? Is this moving faster? Slower? - What should kids be aiming for according to you? Computer Scientist? Biologist? Finance? Construction?
The people best suited for implementing and interfacing with LLMs at the moment are still SWEs and at least for the time being AI is actually probably a job creator for SWEs rather than the other way around. This might change.
And Claude has been invaluable for me to fix trade-related things at home, even complex ones. It actually outdid a locksmith!
The most resilient career is probably nursing. Medicine maybe too, not because it's not technically possible but because doctor lobbies are incredibly strong. Healthcare is the largest employer in most states now and with an aging population that's probably where much of the surplus will go and it's a profession that has really meagre productivity gains (cost disease). So nursing might be the answer.
Disturbingly, AI is set to replace essentially any position that is useful, to the extent that it is useful and somehow some people still think they should adapt themselves to the system instead of working to adapt the system to them!
Basically all that would be left of desk jobs would be those which have unfair legal powers (including via licenses and credentials) or are pure accountability plays. Like politicians, lawyers, aircraft pilots, corporate accountants... And those jobs will suck because people will be accountable for work that is not their own.
These jobs won't require any skills because most people may be able to go through their entire career without doing any work. But they will get paid a lot just for having being selected for their position... While other people who may be more skilled than them might be broke and homeless.
I still don't understand the logic that any job is safe from ai (if it lives up to expectations). Sure, it might not be directly impacted by ai but why is there this expectation that the excess labour from those directly impacted doesnt act to suppress the earning power of other jobs?
Especially considering that the implication is that humans just become a pair of hands with opposable thumbs?. Take the electrician in the article, sure its a skilled job but the barrier into it drops massively imo if you can just take a picture of whatever issue is at hand and ai spits out what is needed, no?
I've always felt that AI's main contribution to eliminating jobs is giving CEOs the ability to do layoffs while trying to both separate themselves from the current economic uncertainty and imply that they are an AI company.
Companies do this all the time. A CEO's job is to convince investors that their company stands to win in whatever the current hot trend is. During bitcoin's crazy run in like 2022 or whatever, a ton of tech companies were hopping on the bandwagon and branding themselves as a blockchain company. Look at Block/Square. The current trend is that AI is hot and the economy isn't. Therefore, it's beneficial to the stock price to tell your investors that you're laying off 50% of your staff because you're AI-powered. Just look at Block/Square. My experience has been that most companies have an incredibly patchwork implementation of AI, and that most of the work that they do (particularly larger companies) isn't made more efficient by using AI.
In a few years, there will be some new hotness, and all companies will be saying that the DNA of their company is whatever that is.
As for the current uncertainty in the job market, when you randomly have 50% tariffs slapped on goods you need and can't readily find available in the US for the same price and find that 20% of the world's oil supply is cut off, you tend to not want to invest in the future. Talking about AI is cheap. Tariffs are expensive.
I'm 20 without a degree, and I am currently working full-time, so I think I have something to add to this conversation.
I wanted to go into tech or commercial aviation as a kid. After COVID I got a reality check on aviation, so decided to aim for SWE. The plan was to study Maths, CompSci and Physics in my country's equivalent of HS, then aim for Physics/CS at uni.
In Spring 2022 (about 6 months before the release of ChatGPT) I realised where things were headed and decided to go into entertainment tech instead, after already completing my first year of college. I'd been volunteering at a music venue as a technician for a few years and it seemed like a good pivot. I dropped out, went to an arts college and studied production, then got a job as a technician at a theatre. After a few false-starts and a while of freelancing as a photographer/technician, I got offered a few full-time positions, ended up taking one in Event AV (events meaning industry expos like CES) - great pay, growing industry, and not really under threat from AI. Everything that can go online has gone online already, but it turns out that businesspeople still like meeting up in-person. I still get to work with awesome technology, but I'm on my feet and working with my hands too. It's different. I'm probably making less money than I would have made in tech 5-10 years ago, but I'm making more money than a few of my friends straight out of CS degrees now.
A lot of my friends are still studying CS, Media, Arts, Languages, and I am glad to be in the position I'm in. I think AI is decimating the value of a degree, and the HE landscape will change a lot in the next decade.
Time will tell if it was a good move, but I think it'll be a while before an LLM can fly panels or coil cable. I'm happy for now.
I'll say invest totally in domain knowledge now. The value of knowing how to invert a binary tree from memory has dropped to approximately zero. Web development as we knew it for the past 20 years is completely dead as an entry level trade. The power is shifting to people with useful knowledge and expertise that isn't about twiddling bits.
Look at recent output from leading edge humanoid robotics projects like 1X/Neo, Figure 03, Skild AI. Also see open published work like MimicDroid, HDMI, GenMimic, Humanoid-Union Dataset, RoboMirror, Being-H0
There is a ton of very useful recent progress with imitation learning and related datasets. There is also some work on learning from large scale video like Youtube.
We are months away from the ChatGPT moment in humanoid robotics where a project launch or demo makes people finally realize that they are general purpose.
The only way we could have AI proof careers is if humanoid robotics were to completely stop progressing. Since it's been advancing very rapidly, that makes no sense.
The industrial revolution is coming for white collar work. I'm finding Marx more and more relevant these days:
"So soon as the handling of this tool becomes the work of a machine, then, with the use-value, the exchange-value too, of the workman’s labour-power vanishes; the workman becomes unsaleable, like paper money thrown out of currency by legal enactment. That portion of the working-class, thus by machinery rendered superfluous, i.e., no longer immediately necessary for the self-expansion of capital, either goes to the wall in the unequal contest of the old handicrafts and manufactures with machinery, or else floods all the more easily accessible branches of industry, swamps the labour-market, and sinks the price of labour-power below its value."[0]
I'm not convinced the current job market turbulence, at least in the US, has anything to do with LLMs. It's just as likely companies are blaming "AI", which has a sort of inevitable feel to it, while they outsource jobs to lower cost countries.
Maybe if college degrees are not so valuable anymore, then school will become cheaper and this will allow more people to go to school. I would hate to live in a world where everyone is a plumber. Nothing against plumbers, but being human is more than unclogging drain pipes and installing toilets, and the one place where humanity's definitions are concentrated most intensely is the university.
I like the choice of firefighter. Though it is a super tough and physically demanding job. When there is lots of uncertainty jobs like these increase certainty. On the west coast more people taking these jobs will more than pay for themselves due to depressing insurance premiums.
We need lots of firefighters on call when landowners do control burns for example. It's a short window.
For years now, I've seen the same old advice repeated: learn a skilled trade and you can support your family.
I started wearing a tool belt for work before I even finished high school. I worked in various skilled trades until I was 38 years old. I made some decent money sometimes, but not often.
Here is the part that people forget to tell you when they give you that advice: learning a skilled trade only pays off if you A) join a union or B) work for yourself.
This is especially true in the Southern US. You can be the best carpenter, electrician, plumber, etc in town, but you won't have healthcare, retirement PTO, you won't be treated like a human unless you join a union (good luck with that in the South) or work for yourself by either being a contractor or starting a company and hiring others to work for you.
However, if someone is truly determine to work in the trades, I always recommend they become a welder. A competent welder can clear $200k+ per year with nothing but a pick up truck with a service bed and their welding equipment and generators.
But other than that, I advise people to avoid the skilled trades unless they can join a union.

Not all of course, but construction work and electrician type work, certainly.
The labour shortages in construction and the energy transformation are huge. And it can't be solved with immigration because there is no housing.
Still if you go blue collar you have to build your own business.
> there is no housing
This could be said of literally anywhere except a ghost town, and it's only true in a very narrow sense. The problem is not housing supply. It's zoning, which is a political decision.

Yes, this is called Baumol's cost disease.
one of the wealthiest dudes I know is a carpenter who loves workin wood. his free time is spent making cabinets and furnature and blasting obscure music
my salary went up about 1.5x
my living costs went up more than 3x and rise each day seemingly.
its fuckin useless. like a scam.
sadly i have injuries that prevent going back to bluecollar job. Id be temped to ask my boss to lower my salary but that also feels fucking stupid.
maybe its time to avoid all taxes and go live in a fucking tent by the side of the road -_-.

1) The supply of work will skyrocket when everyone will flock there for work
2) Demand will plummet as the white collar people who bought these services will loose their jobs and income
And of course if robotics will get solved to an acceptable degree most of those jobs will also get mostly automated.

- Layoffs due to insufficient demand in uncertain economic times
- Companies selling AI need to claim "we are so great with AI we don't need as many people." Layoffs unlock AI budgets.
- It justifies all the capital allocation into AI.
- Companies in the AI industry shock the government into learned helplessness, so they can write policy that is on their terms.
What am I missing?
