Capitalism is not a perfect system. It may be better than all the other systems, but it's not a perfect system.

The U.S. Treasury has got borrowing costs like nobody else has. They can borrow basically unlimited amounts. They can stay there for years and years. These assets will be worth more money over time.

You can go back to tulip bulbs in Holland 400 years ago. The human beings going through combinations of fear and greed and all of that sort of thing, their behavior can lead to bubbles. And it may have had and Internet bubble at one time, you've had a farm bubble, farmland bubble in the Midwest which resulted in all kinds of tragedy in the early '80s.

I love to tell how I'm suffering because one percent we're paying 25 percent of the total. We're not paying 25 percent of the total taxes on individuals. We're paying maybe 25 percent of the income tax, but the payroll tax is over a third of the receipts of the federal government. And they don't take that from me on capital gains. They don't take that from me on dividends. They take from the woman who comes in and takes the wastebaskets out.

As long as you have markets, you'll have excesses. People went crazy with tulip bulbs. They went crazy with the South Sea Bubble, they went crazy internet stocks, they went crazy with the uranium stocks back when I was first getting started. I mean, you know, you're not going to change the human animal. And the human animal really doesn't get a lot smarter.

We have a terrific economy, it's like a great athlete that's had a cardiac arrest.

I mean people -- people don't get -- they don't get smarter about things that get as basic as greed and you can't stand to see your neighbor getting rich. You know you're smarter than he is, and he's doing these things, you know, and he's getting rich, and your spouse is getting unhappy with you because you aren't doing -- pretty soon you start doing it. And so you get what I call the natural progression, the three Is. The innovators, the imitators, and the idiots.
