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.

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.

The U.S. has the most complicated and difficult tax system in the world; we've made it hard to file and pay taxes.

You also get a deduction in America for taking a night school course, growing sugarcane, moving to a new city for a job, replanting a forest, insulating the attic, destroying old farm equipment, employing Native Americans, commuting to work by bicycle - but only if the bike is regularly used for a substantial portion of travel - or buying a plug-in hybrid sports car, or buying a recreational vehicle. I mean there are hundreds of them, and most of them are nuts.

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 higher the rate, the more interest there is in avoiding the tax. Either you move or you shift your profits overseas, as American corporations have proven very good at doing.

The income tax only taxed the Rockefellers, the Morgans and the Vanderbilts. It was aimed at the top 4 percent, and the top rate then in 1913, was 7 percent. Woodrow Wilson had a big ceremony and said, "I'm delighted to be president at the creation of this popular new tax."
