It might be harder for us to charge a higher interest rate, like they do, so it might not be as profitable for us. But we can either compete or partner, like we've announced with On Deck, which does some of the stuff we just spoke about.

They'll [China] probably be a fully developed nation. The road there just is not going to be that easy. You're going from a macromanaged, top-down economy to a market-managed, micromanaged type of economy, with all the potential corruption issues, SOE [state-owned enterprise] reform, and market reform that come with it.

If you look at Detroit, that mayor, it's been a train wreck for 40 years, the population has gone from 2 million to 700,000. This Mayor comes in, and he talked about streetlights, sanitation, jobs, policing, schools, affordable housing. He's doing it all, and it's growing for the first time in 30 years. Literally, one man. But that one man couldn't do it without business. And business couldn't have done it without a political environment where they wanted to improve things. If you had an antibusiness environment there, it would still be down there.

The best way to look at any business is from the standpoint of the clients. So there are these certain basic things that aren't going to change. Companies are going to have needs for equity, debt, advice, FX, and derivatives. Individuals are going to have needs for auto loans, mortgages, something that looks like a deposit account, and the ability to send money to people. Those things aren't going to change.

That's probably good, all things being equal, for emerging markets, not bad, even though it may not be great for all their currencies.

The toughest are people mistakes, when you put the wrong person in a job. Sometimes you're too slow to move them out. Or not getting the right people involved to solve a problem, or doing something out of anger; you learn, just don't do that. But I'd have to say the Whale was one of them, and I would also have to put Bear Stearns and Washington Mutual on the list at this point.

Any good job is a good job. This whole concept of a dead-end job? It's not true. I've heard it my whole life. Jobs lead to dignity. If you're good at the first, then you can get the second. Jobs lead to household formation. Jobs are a better solution for society.
