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.

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.

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.

Starting in the '80s or so, after the United States sharply cut its rates, other countries decided they better do it too, and here's how you do it: you just wipe out the exemptions, the deductions, the credits, the depreciation allowances. And people complain, "Oh my God, it's terrible," but you give them much lower rates and you give them an easier form to file, and people accept that tradeoff.

President Trump repeatedly says that "America is the highest-taxed country in the world." This is an alternative fact. We pay less in taxes, and our government spends less, as a share of our total wealth, than our counterparts in Western Europe and East Asia. But Trump is right when it comes to corporate tax rates; the U.S. corporate income tax right is among the highest in the world.

Our tax code becomes so absurdly complex every 32 years that we have no choice but to scrap it and re-write. The 32-year period is up in 2018. So the time has come. History tells us that we're going to produce a fairer, simpler tax code by 2018.

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.
