Why are high end salaries in the US so high?

Maybe I'm mistaken, but it appears that in pretty much every other developed country salaries >250k USD are nearly unheard of compared to the US where many bankers, doctors, lawyers, engineers, and managers are making that much.

There is a lot of interesting work done on this. Good Economics for Hard Times by Esther Duflo and Abhijit Banerjee discusses ballooning salaries as the result of very low top marginal tax rates after Regan’s presidency and tax reforms. Additionally, many of those top salaries are in the finance sector, and since many of those jobs are in located in New York and London those high salaries would also be located there. Low top marginal tax rates is a large factor in why those salaries are uniquely American, and are not present in other OECD countries. 

Claudia Goldin and Lawerence Katz’s book The Race Between Education and Technology is another good source in the increase in salaries of high skilled workers, but won’t directly address your question.
