I'm not an expert on Islam, but I think there are lots of noble religions whose basic principles could stand considerably more observation in the world of business.

Corporate leaders surely have their problems, I believe that most CEOs are doing their best to hew to the ethical line. The problem is that that line has gotten blurred and that our moral standard seems to be "if everybody else is doing it, it's okay". That's not good enough for me.

While I haven't read economist Robin Hahnel's work, replacing capitalism would be at the very bottom of my list of priorities - to be considered only after everything else had been tried. Improving our capitalistic system however, is at the top of my list and is of course the major theme of "The Battle for the Soul of Capitalism."

We need a federal government commission to study the way our financial services system is working - I believe it is working badly - and we also need more educated investors. There are good long term low-priced mutual funds - my favorite is a total stock market index fund - and bad short term highly priced mutual funds. If investors would get themselves educated, and invest in the former - taking their money out of the latter - we would see some automatic improvements in the system, and see them fairly quickly.

The mistakes we make as investors is when the market's going up, we think it's going to go up forever. When the market goes down, we think it's going to go down forever. Neither of those things actually happen. Doesn't do anything forever. It's by the moment.

I think it's fairly easy to provide a moral defense of capitalism. It has been - over the last 200 years - the underlying basis for enormous increases in productivity and human welfare and rising living standards, particularly in the United States, and in the industrialized nations but in fact, in most parts of the world.

Your success in investing will depend in part on your character and guts, and in part on your ability to realize at the height of ebullience and the depth of despair alike that this too shall pass.
