WHAT? Does that count sick days as well, or is that a myth?
Here in Germany, I get 30 vacation days per calendar year, plus any sick days, and thats fairly normal.
Edit: Sure the absolute salaries here are lower, but the cost of living is vastly different and the social support structures and healthcare are different, too. That should definitely be kept in mind.
I dont need to drive my car a lot, because my city is fully walkable/bikeable, and thats not a super rare thing here. There are a lot of factors.
I feel vacation days are just a basic requirement for happiness, whereas being rich maybe isnt
I mean they have disposable income measures that account for all that as well as welfare programs. In the end disposable incomes in the US make half of the first world look like third world:

You can also see % of that spent on housing, US is lower than most EU countries
