I'm not really sure this person calling in to Michael Savage's talk show, can even qualify as a human. Unfortunately there are entirely too many people who are like this uneducated, over opinionated jackass.
As of July 2009 America's population (well those who were legally counted anyway) was 307,006,550 people.
About 38 percent (or about 1/3 the Population, roughly 102,335,516 people) pay no income taxes. (Again, this number doesn't include people who are in the country illegally or were not counted on the last census)
Around half the population (153,503,275 people) receives some kind of government assistance. (Welfare checks, food stamps, WIC, Social Security, Subsidized housing etc.)
So less than half the US population pays income taxes but receives no government assistance.
