"But most of those people do pay federal taxes" of some sort, such as payroll taxes, said Roberton Williams, a senior fellow at the Tax Policy Center, a center-left Washington think tank, and co-author of a widely cited report last month on who pays taxes. So what. And a lot of them get all of that - and often much more - through housing vouchers, food stamps, "free" job training/cell phones/school lunches, "crazy checks" for their children, etc., etc.
The net effect is that America has a huge parasitic underclass that needs to be weaned off the gubmint teat.
My cousin and her husband made so little, that after standard exemptions and other itemized deductions they paid VIRTUALLY no fed income tax. After the EITC, they netted about $5k.
Which is more than they paid into FICA.
