Even a mediocre stock tends to beat the most generous savings accounts in the long run. But why settle for mediocre when you can buy a market-crushing cash machine? That's the way to start building a richer retirement today.

Online retailer Amazon.com (NASDAQ:AMZN) is one of the stock market's biggest winners since 2001. If you bought Amazon when everyone else thought the company would perish in the dot-com crash, you're sitting on 41% compound annual returns today. Buying Wal-Mart stock or a Dow Jones Industrial Average fund at the same time would only have given you single-digit annual returns -- but even those limping gains would have treated you better than a money market account.

In the video below, Fool analyst Anders Bylund explains why it's not too late to get rich with Amazon's amazing stock.
