What are the odds that people will make smart decisions about money if they don't need to make smart decisions--if they can get rich making dumb decisions? The incentives on Wall Street were all wrong; they're still all wrong.

Everywhere you turn you see Americans sacrifice their long-term interests for a short-term reward.

That was how a Salomon bond trader thought: He forgot whatever it was that he wanted to do for a minute and put his finger on the pulse of the market. If the market felt fidgety, if people were scared or desperate, he herded them like sheep into a corner, then made them pay for their uncertainty. He sat on the market until it puked gold coins. Then he worried about what he wanted to do.

The idea that it's smart to allow Wall Street firms, with this "too big to fail" imprimatur, to become hedge funds again - it's unconscionable. You're essentially saying we're going to take some elites in our society and let them roll the bones in the marketplace, and if it works out they get rich, and if it doesn't work out the taxpayer comes in again. That seems absolutely crazy to me. That seems to be where they're headed. I mean, maybe they're not and I'm wrong. Maybe they'll do sensible things. It's hard to know! There doesn't seem to be a plan.

We have the Google family calendar. Before a week starts, my wife and I sit down to decide who's driving who to school or when can we go out on a date.

The inability to envision a certain kind of person doing a certain kind of thing because you've never seen someone who looks like him do it before is not just a vice. It's a luxury. What begins as a failure of the imagination ends as a market inefficiency: when you rule out an entire class of people from doing a job simply by their appearance, you are less likely to find the best person for the job.
