> An under-rated feature of US cities is the diversity of occupations that can command relatively high incomes.
I find this super interesting, especially when linking salary back to how much society values that job type. For instance it seems that many European countries value societally their teachers and professors, yet it is a rather underpaid profession, all things considered. Similarly, a maitre d’ would be quite well regarded in France or Italie, yet would not command a high-salary.
Thus it feels like your point on there being more diverse sectors being cogent with a comfortable lifestyle in the U.S. rings true.
Veering away from the main point, but I wonder if, as pointed in other comments, that is somewhat balanced by less people being, comparatively, in the poor and very poor category. That is to say, less of a difference between top lifestyles and bottom lifestyles overall. I would need to properly research that though, as salary alone won’t give us that variance.
