The US tech obsession with degrees is stupid and self-defeating. You'll regularly see ads for a web programmer requiring a BS in computer science. Somebody with a BS in comp sci should be able to write a (very simple) operating system, which is not what you need. It's even weirder because some jobs simply require any bachelor's degree, whatsoever, which is how I became a sysadmin after being a classics major. This is just explicit class gatekeeping.
If anything I feel like the US is an outlier in qualification requirements. It feels like every European country requires degrees for every single tech job, whereas in the US you can get by without one or just a BS. The amount of jobs I have seen in the EU that require an MS even though it really shouldn't is insane. I think every single technical ESA role requires an MS at minimum, whereas you can easily work at NASA with just a BS, which doesn't really make much sense.
Also you can still go to community college/a state school to get a BS? Or join the Army or something, take a low risk MOS, get them to fund your bachelors. The US is way less class prohibitive and has far more class mobility than the EU as a whole so I'm not sure what you're talking about.
The US has significantly lower social mobility than most of Europe, though I think people kind of ignore that and pretend the opposite is true.
It's a lot easier to get in to college in the US than in most of Europe, but it costs a whole lot more (like requiring a degree in the first place, it's a kind of social gatekeeping). I think nowadays like 60% of high school grads attend some amount of college, but only about half of those get an actual degree.
