The US is top 10 in PPP gdp per capita, and almost all of the states that are higher up are either tiny oil and gas states (eg Qatar, Brunei, Kuwait) or small states that focus on financial services for much larger areas (Luxembourg and Ireland for the EU, Singapore for the indopacific).

Seriously, the highest population in any state with a higher GDP per capita than the US is the UAE.

#1? Maybe not, but it's certainly pretty close in any useful discussion.
