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.

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.

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.

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.

When it comes to taxation, Americans are still banging out letters on a typewriter and dropping them in the mail box while everybody else has moved on to texting and Instagram.

Relative to the world's other advance democracies, Americans get off easy on tax day. Of the 35 richest countries, the U.S. ranks 32nd in total tax burden.
