I keep hearing these pundants on the news saying that something like 50% of working Americans dont pay any Federal tax. My son worked a part time job last year as a short order cook and grossed 13,000$. He just got his taxes done and he had to pay about 700$ in Fed tax. Am I to believe that 50% of the working class is making far less than 13000$ per year that they find themselves untaxed?
