Subject: Re: Biden's billionaire tax rate fact checked
In the aggregate they don't have a low proportion, as the data shows.

They do. They pay a much lower proportion of their earnings in federal taxes than is typical, because unlike nearly everyone else in the country their earnings are almost entirely in the form of unrealized capital gains. Everyone else has to pay social security and medicare and income taxes on their wages and salaries; billionaires accumulate their wealth through appreciated assets.
