Using State+Provincial Level HDI as a proxy, entire States+Provinces [0][1] are comparable to entire Tier 1 European countries [2] on a socioeconomic basis.
When you look at purely economic indicators such as GDP/GDP Per Capita the same story holds [3][4][5]
If you're complaining about urban planning around walkability, you will need to specify which European cities you are comparing to, and which American cities as well.
It's unfair to compare a Tier 2/3 North American city like SLC or Phoenix or Vancouver to London or Paris when those cities are the Primate Cities of their entire country. Comparing cities like London/Paris/Frankfurt to NYC or Berlin to DC or Munich to the SF Bay makes more sense.
And finally, the kind of suburbanization you're complaining about is VERY common in Europe as well.
