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.

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."

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.

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.

We cut tax exemptions in 1986, it was the most admired tax reform in U.S. history. Congress and the president worked together then to eliminate scores of loopholes and exemptions and deductions; this made taxes much simpler, and allowed a major cut in tax rates.

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.

I really like the idea of consumption tax, and most countries have a pretty serious consumption tax. It's called a value-added tax or a goods and services tax ... It's a sales tax. It doesn't tax labor, it doesn't tax savings or investment - it taxes consumption.
