There are plenty of books on making money by men and women who havent made much. Thats exactly why I like this book by J. Paul Getty, there is no disputing the authors credentials. He wrote it to convince young businessmen that there are no sure-fire, quick-and-easy formulas for success in business, that there are no ways in which a man can automatically become a millionaire in business.
And specifically when it comes to stock investments he discusses why the average person will not attain wealth in the stock market. The average person may risk a little of his or her capital and if the investment doesnt work out the person loses a little. It is precisely this kind of risk that everyone can take that negates the creation of wealth. If the investment works out, the gain is usually little. You would have had to invest a substantial amount in a superior asset/stock in order to benefit from the movement of the share price and this is the kind of risk that few are willing to accept.
