In the United States, unlike any other advanced democracy, money really talks. Our Supreme Court has said that spending money on politicians is a form of free speech. No other court has said that.

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.

It turns out a VAT - a value-added tax - is a very easy tax to collect and a very hard tax to evade. It's a really good idea. It was invented about 60 years ago in France, of course. Because they're so good at taxing. They had a business tax that was easy to evade, and the head of the French IRS invented this value-added tax, which is very hard to evade.

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. It's outrageous the burden we put on people, and guess what, you go to Europe, you go to Japan, it's 15 minutes and costs nothing.

It was an easy thing to tax for a young country. And then gradually we moved to property taxes, manufacturing taxes, and the income tax was the answer to a populist demand: Let's go after the rich guys. We got into World War I, and they raised the rates and started taxing the rich. Then we got into World War II, and that's when they taxed everybody, because they just needed more revenue.
