Facts are pesky things.

For 2013, families with incomes in the top 20 percent of the nation will pay an average of 27.2 percent of their income in federal taxes, according to projections by the Tax Policy Center, a research organization based in Washington. The top 1 percent of households, those with incomes averaging $1.4 million, will pay an average of 35.5 percent.

Those tax rates, which include income, payroll, corporate and estate taxes, are among the highest since 1979.
