I used to be opposed to the idea of social entrepreneurship. I said, you know, let business be business, and philanthropy be philanthropy. Keep the two separate, don't mix it up, and this is what I did, and I did that rather successfully, but I now recognize that actually you do need to mix it up and I think there is room for social entrepreneurship.

When you sell options, you get paid for assuming risk. That can be a profitable business, but it does not mix well with the risks inherent in a leveraged portfolio.

The securitisation of mortgages added a new dimension of systemic risk.

The agents were more interested in maximising fee income than in protecting the interests of bondholders. That is the verity that was ignored by regulators and market participants alike.

There is a resurgence of anti-Semitism in Europe. The policies of the Bush administration and the Sharon administration contribute to that. It's not specifically anti-Semitism, but it does manifest itself in anti-Semitism as well.

There is no doubt that the countries that now have a very large debt have not introduced the kind of structural reforms that Germany did and are therefore at a disadvantage. But the problem is that this disadvantage is becoming even more pronounced through the punitive policies in place.
