Beware of geeks, you know, bearing formulas.

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.

We had the great depression, we had two world wars, we had the flu epidemic. We had oil shock. We had all these terrible things happen. But something about the American system unleashed more and of a potential to human beings over that hundred years so that we had a seven for one improvement in - there's never been any - I mean, you have centuries where if you've got a 1 percent improvement, then it's something. So we've got a great system. And we've got more productive capacity now than we ever have.
