First of all, let’s try to avoid American-bashing, and stay respectful to everyone.
I’ll start: for me it’s the tipping culture. Especially nowadays, with the recent post on [email protected] with the 40% tip, it just seems so weird to me to have to pay extra just so that menu prices can stay low.
Lifelong American here - I do love it here, though as you point out there are definitely some stressful flaws.
Healthcare here is messed up. Not the quality (which is typically very high), but the price. Having insurance tied to employment never made sense to me either.
Personally, I actually love driving and owning a car. I just think cars are really cool and I like wrenching on them. Everything I could need is within a 10-15 minute drive and I never have to worry about there not being enough parking. That said, you are correct that car ownership is basically required - although I have been to cities in the US that have decent public transportation. Not European level good, but decent.
At my job I get 4 weeks paid vacation and “unlimited” sick days (they say unlimited but of course they have the ability to deny them if they find you are abusing them). My bosses will actually hunt people down who HAVENT used all their vacation days and encourage them to do so. They have realized that productivity is tied to employee happiness so they try to keep us happy. Now, none of that is government mandated but I just mention it to prove that not everyone here has a job that treats them like crap. I agree that this stuff should be guaranteed though. For reference, I work in IT and make less than 100k.
Tipping is definitely a weird thing and I would be glad to never have to think about it again.
