Reply #7: Maybe someone can help me find a piece of data.

[AnnaLee]

Yesterday I started obsessing on the phrase/talking point - "America is still the richest country in the world." It struck me that I would like to know just who or what is meant by "America". This morning I decided to find out how much of American "wealth" would disappear if the "rich" and the big companies all decided to change citizenship or registration at the same time. (Example, the American owned skyscrapper is no longer American owned.) It turns out that I can find a record of both financial and tangible assets of ordinary Americans but I can only find data on the financial assets of the corporate/rich.

This guy seems to have had a similar question with a similar problem with this piece of the pie:
