What if I told you, that even mentioning this shows how little free time people get in the US?
There is actually no SWE job (and I do mean actually 0 positions, I watch job postings way more than average person) in CZ that offers less than 5 weeks of paid vacation. When you look for companies that give actually nice benefits you can get 7-8 weeks, big chunk of it being sick days that you can claim whenever you want.
And that all is on top of MUCH longer parental leave, often shorter work week (lol @ 40h a week being noteworthy), much more leeway given to people with health issues and generally shorter commutes.
Not even mentioning difference in cost of living . . . The values are just different here.
