His comment on "first dollar" is wildly deceptive as well. An income tax never applies to all 'revenue' but only to 'net income'.
He entirely skips over the difficulty of defining 'income' as revenue minus all VALID business expenses. This is the root of the IRS' most intrusive activities for businesses. He claims his plan would save the $250B in compliance costs, just as removing all taxes from business vis-a-vis the FairTax would. As though there are no compliance costs in satisfying the IRS that all your expenses -- and hence your net income reported -- are valid.
