I think we all ought to be careful about too much generalization on this issue, even as I confess to painting with a pretty broad brush myself!

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.

Successful investing is about owning businesses and reaping the huge rewards provided by the dividends and earnings growth of our nation's - and, for that matter, the world's - corporations.

It's very difficult for any particular segment of the stock market to sustain superior performance. The watch word for our financial markets is, "reversion to the mean" i.e. what goes up must come down, and it's true more often than you can imagine.

While the apostles of the new so-called "behavioral" theory present ample evidence of how often human beings make irrational financial decisions, it remains to be seen whether these decisions lead to predictable errors that create systematic mispricings upon which rational investors can readily and economically capitalize.

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.

In the long run, investing is not about markets at all. Investing is about enjoying the returns earned by businesses.
