Total retail and food services sales, according to the US Census Bureau here, in 2008 came to $4.4 trillion. (For 2010, the annualized estimate based on 8 months' of data is running at $4.6 trillion).
To replace the federal tax revenue of $2.5 trillion in 2008 solely on the back of consumption taxes, such as a national sales tax, would imply a national sales tax rate of . . . 57 percent. Unthinkable, unless you are Greece.
Herman Cain doesn't advocate that. But his idea of a 9 percent sales tax would have generated, at most, a paltry $400 billion in 2008. Coupled with about $765 billion from a 9 percent income tax on about $8.5 trillion in total adjusted gross income in 2008, the business community would have been on the hook for the missing $1.3 trillion in 2008 federal revenue, when it actually contributed only $300 billion in taxes that year.
A 333 percent increase in the tax liability of American business sounds like something only a commie like Obama would propose.
Herman Cain's numbers don't even come close to matching the problem which we are facing.
