If I'm making six figures as a dev in the US, I probably have fairly generous benefits, including healthcare, vacation, parental leave, retirement plan contributions, disability insurance, etc. And I'm probably paying less in overall taxes than most Europeans (though it really depends).
Of course, I don't have the safety net things that lower-income Europeans do, but I almost certainly don't need them.
So what would the equivalent person in the EU making half as much be getting from their government that I'm not getting from mine?
(Btw, this isn't an argument for the US approach being better overall, but just which system is better for the selfish high-income professional)
