What about three weeks of extra annual leave, public holidays, real healthcare with no bullshit co-pays (and unlimited sick days, they don't count towards "pto"), a maximum 35 hour work week... Because that's more like what it would look like for a higher value job like that. Depends on the country and the job, of course. But in my case in the UK right now, and in my last job in Germany, my total "pto" in US terms has been roughly two months. (Which is a lot even here, but it's not by any means unheard of, and easy to get if it's a priority to you). Doing a job with an average salary of about 100k in the US, and I get paid a little over 50k £ for it, which is about 1.5 times the median salary here, so even after the recent inflation it affords a pretty comfortable lifestyle, it's enough money to pay the mortgage and take holidays to the continent in my ample time off.
Sorry, this turned into a bit of a rant, but tldr: it's not just "an extra week"
Still not worth it. I broke my leg 3 years ago I paid $2.4k total with my insurance. Today it'd be more like $5k as my insurance isn't as good, but it would still be worth it to stay in the US even if I broke a bone every 3 months! However, two months of PTO is certainly something. But to be honest, my mentality is in a place where I'd probably end up doing some work on the side if I honestly had 8 weeks of PTO. Even when I had unlimited PTO, I only took like 4-6 weeks a year.
I think broadly speaking, if you make under $120k/year in the US, your quality of life will be better in Western Europe just because of the social safety net and worker's protections. And this is especially true if you're planning on having children.
