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.

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.

I want our pie to grow all the people, but if some other guy's pie is growing a little faster, that's terrific.

I think it's terrible for people in effect to say that income from investment should be taxed at a much lower rate than income from labor.

As long as you have markets, you'll have excesses. People went crazy with tulip bulbs.

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.

If you owe money, you can't pay them out. You just pay for everything, you do smart things, you eventually get very rich. If you do smart things and use leverage and do one wrong thing along the way, it could wipe you out, because anything times zero is zero. But it's reinforcing when the people around you are doing it successfully, you're doing it successfully, and it's a lot like Cinderella at the ball. [...] And everybody thinks they're going to leave at two minutes to 12.
