A Times news article about rich people includes the sentence, "In Britain, which, unlike the United States, does not tax individuals on their reported global wealth, the number of investor visas rose by a quarter in the first three-quarters of 2013."
That's a strange formulation — the U.S. in fact doesn't tax individuals on their "reported global wealth," but on their global income. The difference between income and wealth is something that reporters and public policy makers often get confused about.
