If you ask any economist, they'll tell you all the mortgage interest deduction does is raise the price of the house. So a couple is out looking at the house, they say, "Oh, we love this house, but we couldn't make the monthly payment." And the realtor says, "Yeah, but you're going to get a tax break." So people pay more than they would otherwise. You take a loss even though you're making a gain.

Americans spend about 6 billion hours a year collecting the data and filling out the forms. We spend $10 billion to H&R Block and other preparers. And on top of that, $2 billion in tax preparation software, which still takes hours of work.

I mean there are hundreds of them, and most of them are nuts.

The Value-Added Tax, a sales tax that applies at every level of business transactions, is an easy tax for governments to collect, and a hard tax to evade. So it makes the job of raising revenue easier. The revenues from the VAT can then be used to lower taxes on income and saving and investment. The Value-Added tax doesn't penalize work or saving; it's a tax on buying stuff.

France, they're the world champion at soaking the rich on taxes. And at one point, they had what they called a hyper tax, 75 percent, and Gérard Depardieu and many others left the country.
