O'Reilly has been touting a "consumption tax" for a few weeks now, even though most of his guests disapprove. But he claims that there is a "trillion" in untaxed income in the black market that at least could be taxed on the back end. I'm not sure about his figures, but I understand what he's getting at. Drug dealers and people who run cash businesses )illegally) in the red are not paying their "fair share". I believe he's suggested 2 percent.
Consumption tax is like a value added tax (VAT)...The problem in other countries with this kind of tax is that it always starts out low and attractive, then the greedy politicians just keep raising it a little at a time. Many of the countries where this was implemented started out at 2-3%, and now are up to 15-18% or more.
