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.

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.

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.

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.

If you get rid of all these giveaways and loopholes and deductions and credits, then you can sharply lower the rates.

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 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.
