But 300 million Americans, their lending institutions, their government, their media, all believed that house prices were going to go up consistently. And that got billed into a $20 trillion residential home market. Lending was done based on it, and everybody did a lot of foolish things.
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.

That would be nice if [people] stuck [treasury bills] all under a mattress, but they got to buy something with them. Sometimes they buy a treasury note, sometimes they set up sovereign wealth funds. They can do all kinds of things. They can buy our companies here. As long as we consume more than we produce, and we trade away little pieces of the country daily, they're going to own something.

I was lucky enough to be born in a time and place where society values my talent, and gave me a good education to develop that talent, and set up the laws and the finanical system to let me do what I love doing-and make a lot of money doing it. The least I can do is help pay for all that.
