The US? GDP of the UK is close to 3 Trillion USD.
Ohio, NJ, Nebraska, Maine, and Florida combined have a lower GDP.
in fact, it seems like California is the only state which has a higher GDP than the UK.
Or is wealth measured another way..?

It's pretty misleading to frame this as though the UK is drastically lower than any other comparable countries though. The UK's GDP per capita is similar to Canada, France, Israel, Japan. And that doesn't even get into whether GDP is actually a realistic measure of how "poor" a country's people are (c.f: Ireland, which has a much higher GDP per capita than the US, but similar material conditions to the UK).

GDP is a silly metric anyway. GDP(PPP) is ightly better, and IDHI is imo the best way to chose a country you want to immigrate to for your children.
