1. This needs to be GDP at purchasing power parity, not nominal currency rates. How far does your money actually go?
2. Compare Danes to Danish Americans. Swedes to Swedish Americans. Germans to German Americans. You will quickly see that the US is far wealthier per capita. There are very few European countries wealthier per capita than the US. Luxembourg (tiny little tax haven), no doubt Monaco (same deal), Norway (world’s 4th? largest energy exporter with tiny little 4.5 million population), etc.
Germany? France? Belgium? The UK? Not even close. The US is much wealthier than they are per capita. If you doubt it just go there and look around. I could see the US was significantly wealthier when I last lived over there in 2004. The gap has only grown much wider since then.
Luxembourg is significantly smaller than metro Atlanta (just under 1000 sq. miles vs. 8376 for the Atlanta MSA). And has a relatively tiny population, only 680,000 vs 6.3 million. Just to give a sense of scale for your tax haven.
GDP per capita is not a good measure of individual “wealth” as it takes the net GDP and divides it by population - so if in a population of 100 people, 1 guy earns $99,901,000 and the others earn $1,000 each, then the GDP per capita is $1 million, but that is not the true wealth of each.
For instance, the USA’s GDP per capita is $76,600 and the GDP per capita of the Republic of Ireland is $129,000. But the individual Irishman is NOT wealthier than an American - rather it is because the GDP is driven largely by multinational corporate profit accounting rather than local household income
There are better metrics for “wealth” - like Median Wealth per Adult.
If you look at Median wealth, you get
Luxembourg: ~$395,340
Denmark: ~$216,098
The UK: ~$176,370
France: ~$146,017
Norway: ~$142,501
USA: ~$124,041
Sweden: ~$111,270
Germany: ~$66,735
India: ~$3,457
Or, I prefer Median Disposable Income - adjusted by PPP from statranker.com
then
luxembourg - $49,748
USA $46,625
Norway $41,621
Germany $32,246
Denmark $31,324
France $29,759
Sweden $28,859
UK $26,687
I think this is a better one than “household wealth” - as for household wealth they include property owned and property prices in the UK are sky high while Germans mostly rent.
This last statistic agrees with your point that Americans ARE richer on average - but it doesn’t have the glaring errors that GDP/capita have
