“the wealthiest Americans” already pay more than their “fair share” in taxes. According to the Congressional Budget Office, the top 1 percent of US earners already pay 22.3 percent of all federal income taxes (based on 2009 figures), even though their share of total income earned is just 13.3 percent. The top 2-5 percent of American earners pay 17.3 percent of the total share of federal income taxes paid, even though their share of total income earned is 12.5 percent. The top 20 percent of Americans pay 67.9 percent of total federal income taxes, while their share of total income earned is 50.8 percent.
