You know the rule of 72, divide the number into 72, any number you want, and that's how long it will take your money to double.

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.

I'd be the first to agree that capitalism bestows its blessings unevenly. But that wouldn't persuade me to think it was a good idea to do away with those blessings in their entirety. That said, there is lots of work to be done to make capitalism work better, and to broaden its blessings far more widely not only in America, but all over the globe.

Hint: money flows into most funds after good performance, and goes out when bad performance follows.

Index funds eliminate the risks of individual stocks, market sectors, and manager selection. Only stock market risk remains.

If it is hard to imagine that 20% of losses on the stock market, you should never participate

I believe that the mutual fund industry's biggest shortcoming is too much focus on the momentary price of a stock - an illusion - and too little focus on the intrinsic value of the corporation - the ultimate reality. I'm comforted by the fact that Warren Buffett feels the same way.
