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 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.

People love leverage when it's working. I mean, it's so easy to borrow money from a guy at X and put it out at X.

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.

The American worker is more productive than he's ever been. We've got more people to do it. We've got all the ingredients for a sensational future. It's just that right now the athlete's on the floor. This is a super athlete.
