Thomas Aquinas defined the human soul as the core of our being, and the power that brings our characteristics into unity so the soul of capitalism - in its own temporal world as contrasted to the spiritual world of human beings - is what defines the core of the system and the factors that unify to produce the wonderful world that we are blessed to live in.

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.

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.

If you're very talented and keep winning, you'll do just fine. It may take a while. But the talent is hard to identify and talent is hard to tell from luck. There's an awful lot of luck in this business. Past performance is not helpful in judging future performance.

Investing is not nearly as difficult as it looks. Successful investing involves doing a few things right and avoiding serious mistakes.
