Yet economic mobility, measured in terms of the likelihood that you die in a different income decile than you were born into, is lower in the USA than almost anywhere else in the developed world.
How to reconcile? It's fairly easy ... there aren't that many millionaires. The US has a society, culture and economy that allows for their occurence perhaps "better" than most other places. But this doesn't reflect the likely economic pathway that most of the population experiences in life.
The deciles are much further apart and the ceiling is massive. Compare the medians of all the countries (the US is at or near the top) then compare the 90th percentile and the US is heads and shoulders over the next highest.
Which proves that talking about millionaires is no longer that socially relevant thanks to inflation. Somehow ten-millionaire doesn't have quite that ring though.
