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.

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!

Ask yourself: Am I an investor, or am I a speculator? An investor is a person who owns business and holds it forever and enjoys the returns that U.S. businesses, and to some extent global businesses, have earned since the beginning of time. Speculation is betting on price. Speculation has no place in the portfolio or the kit of the typical investor.

We are facing incredible challenges in the economy of the U.S. and the economy of the globe, but the stock market, we never know whether it's over-discounted or under-discounted or got exactly right its anticipation.

Managed funds are astonishingly tax-inefficient.

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 would always advise young people to follow their star - not my star. They have to live their own life. If they decide they want to go into the investment business, do it, but make it a better business than it is today.
