Another eye-popping number was the percentage of Americans who don’t pay income taxes, which now accounts for nearly half of the U.S. population. Meanwhile, most of that population receives generous federal benefits.

“One of the most worrying trends in the Index is the coinciding growth in the non-taxpaying public,” wrote Heritage authors Bill Beach and Patrick Tyrrell. “The percentage of people who do not pay federal income taxes, and who are not claimed as dependents by someone who does pay them, jumped from 14.8 percent in 1984 to 49.5 percent in 2009.”

That means 151.7 million Americans paid nothing in 2009. By comparison, 34.8 million tax filers paid no taxes in 1984.
