1 Luxembourg $4,089
2 Norway $3,678
3 Austria $3,437
4 United States $3,263
5 United Kingdom $3,065
6 Belgium $3,035
7 Sweden $3,023
8 Ireland $2,997
9 Finland $2,925
10 South Korea $2,903
11 France $2,886
So basically, you get better, less expensive, more effective* mostly free national health care, better social security, better standards of living, shorter working days (8-4/9-5 vs 8-5/9-6), and 6 weeks vacation.
For that you surrender $387 a month. In france.
It costs you less in Sweden, Belgium, and UK. I think working conditions in Ireland are currently worse than in the U.S.
It costs you nothing in Luxembourg (atypical), Norway, and Austria.
*While exceptions exist in the U.S., they are usually for very expensive treatments. In general, the mortality rate, child and infant mortality rate, and lifespan are better in the listed countries. U.S. health care outcomes for the bottom 80% are worse than 28 or 29 other 1st world countries.

More generally (not in response to your post), you can't negotiate vacation in the U.S. It's a benefit- it's hard coded in the software. I did it once- getting a week without pay- after five years my new manager just arbitrarily cancelled it when I got my paid 3rd week. There was no one to appeal to if I wanted to remain employed.
