What would the Founding Fathers think about this? 47% of American households pay no federal income tax. Five years ago it was 40%. 20% of US households receive 75% of their income from the fedgov. Another 20% receive 40% of their income from the fedgov. The top 5% of taxpayers pay 60% of all fed income taxes. The top 10% pay 75% of all fed income taxes. The non-taxpayers will soon outvote the taxpayers.
