If you really think that houses prices are going to go up next year and the year after, you feel if I don't buy it this year, I'm going to have to buy it next year. [...] And when somebody makes it very easy for you to do it by saying you don't really have to put up my money, you can lie about your income a little, or we'll give you 100 percent mortgage, you're going to do it, because everybody that's done it has been proven right. You have what they call social tools, and, you know, you're going to feel like an idiot if you didn't do it, because the house cost more.

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.

You may be very mad at some guy that walked away with a huge golden parachute, but that really isn't the important thing. I mean, if Pearl Harbor came along, you could have said the planning was wrong by the military ahead of time or maybe the battleships shouldn't have all been in the harbor and all that kind of thing.

You could have these crazy Internet valuations in the late 1990s, but they prove themselves out in the market. The next day they were selling for more than they were the day before, and people said, you know, you're crazy if you don't get in on this. So it's very human.

I mean the whole economy just comes to a grinding halt. Competence in markets and in institutions, it's a lot like oxygen. When you have it, you don't even think about it. Indispensable. You can go years without thinking about it. When it's gone for five minutes, it's the only thing you think about. And the oxygen has been sucked out of the credit markets.

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.

It will be good for us in the long run, and I mean there are six and a half billion people in this world. And it's great for 300 million to keep enjoying more and more property, but I think it's terrific if the remainder do. And I think if they can learn something from us in terms of our system, and I think they have, they are learning more about how to unleash the potential of their citizenry to turn out more goods and services that their citizens want or that we want, I think that's terrific.
