Beyond that the differentiators are working hours/flexibility and healthcare. A household in Texas might have quite a good life in many respects with an income of 60k/year, but do they get 6 weeks off, flexible working hours (useful if you have kids), and paid maternity/paternity leave that lasts more than a few weeks? In the US if you want/need that extra time away from work you might need to take time of work or go part time, causing a drop in income and perhaps company sponsored healthcare, but in many European these things are available by default to fulltime employees.
