I hadn't thought about the fact that one reason so many people aren't paying federal income taxes is because of R tax policy. This guy has:
For what it’s worth, this division of “makers” and “takers” isn’t true. Among the Americans who paid no federal income taxes in 2011, 61 percent paid payroll taxes — which means they have jobs and, when you account for both sides of the payroll tax, they paid 15.3 percent of their income in taxes, which is higher than the 13.9 percent that Romney paid. Another 22 percent were elderly.
So 83 percent of those not paying federal income taxes are either working and paying payroll taxes or they’re elderly and Romney is promising to protect their benefits ... ... Part of the reason so many Americans don’t pay federal income taxes is that Republicans have passed a series of very large tax cuts that wiped out the income-tax liability for many Americans. ... So whenever you hear that half of Americans don’t pay federal income taxes, remember: Ronald Reagan and George W. Bush helped build that. ...
Some of those tax cuts for the poor were there to make the tax cuts for the rich more politically palatable. “Do you think we wanted to include a welfare payment to people who don’t pay taxes and call it a tax cut?” A top Bush administration official once asked me. “No. But that’s what we needed to do to get it done.” But now that those tax cuts have passed and many fewer Americans are paying federal income taxes ..., Republicans are arguing that these Americans they have helped free from income taxes have become a dependent and destabilizing “taker” class who want to hike taxes on the rich in order to purchase more social services for themselves.
The antidote, as you can see in both Paul Ryan and Mitt Romney’s policy platforms, is to further cut taxes on “job creators” while cutting the social services that these takers depend on. ...
