Relevant editorial inIvestor’s Business Daily in Dec 2013:
How Much Redistribution Is Enough?
“The CBO study breaks down the country by income into five equal groups, or quintiles. It found the top 40% paid more than 100% of all the income taxes, while the bottom 40% had a negative income tax. These families got more money through various refundable tax credits, on average, than they paid in income taxes.
Even when you include payroll and other federal taxes, the poorest group paid just 0.4% of all federal taxes, while the wealthiest paid 70%.”
CBO:Top 40% Paid 106.2% of Income Taxes; Bottom 40% Paid -9.1%, Got Average of $18,950 in ‘Transfers’
