There's a tradeoff. Yeah, I lose the deduction that I really like, but my tax rate is going to go down, and I don't have to fill out that form anymore. It's much simpler, rates are lower, and that tradeoff has worked in many countries. Many countries have just cleaned house of all those exemptions in order to provide lower rates, and people buy it.

It used to be that we taxed property - zapped farmers basically. And there were very rich people who didn't pay that much tax. So in 1913, they put in the income tax. It was incredibly popular. The tax we love to hate today.

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.

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.

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

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.
