Californian in Dublin - I feel embarrassingly overpaid in Ireland. But every time I go to the US, I feel embarrassingly underpaid.
My wife and I went from California to Ireland, then back to California for a year, and when she used up her whole 1 week of vacation and we realized even in tech we'd never afford a house where our kids could walk to a decent school, we moved back to Ireland.
I'd make 2-3x as much in the US, but I wouldn't be happy.
Also - "TRUE vacation " - WHAT THE FUCK is up with Americans who think it's appropriate to bug people about work on vacation. Or to have "unlimited" vacation policies and act surprised when someone wants to take what would be _the legal minimum_ in a lot of other countries. And sticking people on pagerduty half their goddamn lives. Seriously, fuck right off to hell.
It's evil.
