Or maybe you actually get to work on technology most/all of the time, doesn't mean you enjoy it.
Sure, working in R&D is probably pretty awesome for most tech guys there, but what about the guy maintaining that PHP app from 10 years ago that is "absolutely critical" for that one customer?
My point is you can either give a shit about your job or not. If you don’t, don’t expect to do anything innovative or produce a lot of value. If you’re cool with that, so am I.
Just don’t complain in a few decades when you have to cut back social programs.
You seem to have conflated working overtime and not taking vacations with "giving a shit about your job".
Sure, not giving a shit about your job wont give you innovations. But working overtime and not taking vacations wont give you innovations either. It's totally orthogonal (if not detrimental to healthy worklife and innovation) issue to whether you're passionate about your job or not.
Case in point:
(a) No innovations come out of the hundreds of millions of Americans who work BS jobs, think them as BS jobs, but still being culturally or openly forced to work overtime and to only take meagre vacations. No innovations come from office drones who share all that, and Japan has not made any dent in CS/IT, despite working even more and having worse life balance than Americans. Working overtime is good for production lines, mindlessly churning out stuff.
(b) Innovations come just fine from companies with a healthy work-life balance. Heck, most of the great CS and IT innovations, that in substance and impact no FAANG or BS "unicorn" ever matched, came from places like IBM, Bell Labs and the Xerox Parc, of the 60s and 70s, great places to work, with good work life balance, and research focus -- not toxic overtime environments.
The idea that innovation and liking your job is not compatible with worklife balance or EU-style vacations, is a toxic and dangerous to humanity (ito ndividuals and their families, for starters), idea.
It makes for good profit and docile workforces though. Whatever makes the US employer sleep well at night...
The first is a tiny sliver of people who make good money doing interesting, possibly even fulfiling work. Like say running their own business, or building great new tech.
The larger slice though don't have this. They work long ours doing meaningless boring tasks for long hours and low wages. Think amazon warehouse, and any service level job.
There's a middle ground for qualified trades - like say plumbers - but that's getting eroded.
So when comparing things like leave, ability to fire, heath insurance etc, it's worth understanding that your view in those things is relative to your job.
For the lucky few millionaires, the US is great - it's a very easy place to live if you are rich. But for the rest Europe with lots of vacation time, shorter working hours, free health and education is a lot more appealing.
