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.

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.

Mortgage is one of the most popular deductions. It costs the Treasury about $103 billion a year. Now that's money we could use to treat wounded veterans or reduce the deficit or fill the border. Instead, we give it a subsidy to homeowners, and it goes mainly to the richest homeowners in America, because only one third of Americans itemize their deductions. It doesn't work. Many countries have gotten rid of the mortgage interest deduction. Almost all of them have higher homeownership rates than we do.

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.

If your employer pays your health insurance, that's not counted as income to you. And any economist would say that's your income, because they'd pay a higher wage if they didn't take it. That's a huge loss to the Treasury.

We have the most expensive compliance system in the world. The IRS brags that they spend 35 cents for every $100 they collect. They're very efficient collectors. And the reason is they stick the real cost on you and me.

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.
