On the flat tax, the more you compress the tax rates, the more you untax where the income is really made, at the top of the pyramid.

Today, people are having to spend so much of their money, to acquire a house and to get an education that they don't have enough to spend on goods and services, except by running into yet more debt on their credit cards and other borrowings.

When Hillary Clinton said she's going to do just what Obama does and we're going to continue to recover, most people know that we're not recovering at all. We're shrinking.

The concept of productivity in America is income divided by labor. So if you're Goldman Sachs and you pay yourself $20 million a year in salary and bonuses, you're considered to have added $20 million to GDP, and that's enormously productive. So we're talking in a tautology. We're talking with circular reasoning here.

Europe is creating the flight of refugees that's tearing it apart politically, and leading rightwing nationalist parties to gain power to withdraw from the Eurozone.

Everybody would be better off if they could buy housing for only, let's say, a carrying charge of one-quarter of their income. That used to be the case 50 years ago.
