The blowback against a bailout of Lehman would have been fierce. It is often forgotten, but the prevailing wisdom the day after Lehman fell was that its collapse was a good thing.

I started, actually, in journalism when I was - well. I started at the 'New York Times' when I was 18 years old, actually, but really got into journalism when I was 15 years old and had started a sports magazine which was trying to become a national sports magazine.

The rating agencies historically actually did a pretty good job rating regular bonds.

There's a good argument to be made that companies that are private, where they're run by partnerships, where everybody has true stake in them and they're not playing with other people's money, that by default it's a safer system, because you really have skin in the game. You really own the company.

Debt, we've learned, is the match that lights the fire of every crisis. Every crisis has its own set of villains - pick your favorite: bankers, regulators, central bankers, politicians, overzealous consumers, credit rating agencies - but all require one similar ingredient to create a true crisis: too much leverage.

I think, with Hank Paulson, the concept of a bailout was anathema to him from day one. He was a Republican; he's a free marketeer. He believes in capitalism, and part of capitalism is believing in failure. And so the idea of bailing out an institution, I think, went against every part of him.

Wall Street is littered with clever plans to use financial instruments to change behavior - carbon trading, for example. Some have changed the world, and others failed miserably.

In truth, Wall Street is in for a radical makeover. Fewer people, lower margins, lower risk, lower compensation - and ultimately, fewer talented people. It is likely to change the culture of an industry that for nearly a century has been the money center of the world.

I don't sleep well. I'm a very nervous - by my nature - anxious, almost paranoid person and reporter.

I'm probably a believer in abandoning too-big-to-fail firms or breaking them up in some way so that the system can try to take care of itself. I imagine you're not going to get there, and therefore, I suspect regulation is what's going to be required.

By now, it seems as if everyone has already read Thomas L. Friedman's 'The World Is Flat: A Brief History of the Twenty-First Century.' It changed the way we think about global business, competitiveness and the implication for far-flung economies, governments, education and more.
