The worst continued to worsen. What looked one day like the end proved on the next day to have been only the beginning. Nothing could have been more ingeniously designed to maximize the suffering, and also to insure that as few people as possible escape the common misfortune. The fortunate speculator who had funds to answer the first margin call presently got another and equally urgent one, and if he met that there would still be another. In the end all the money he had was extracted from him and lost. The man with the smart money, who was safely out of the market when the first crash came, naturally went back in to pick up bargains. The bargains then suffered a ruinous fall. Even the man who waited for volume of trading to return to normal and saw Wall Street become as placid as a produce market, and who then bought common stocks would see their value drop to a third or a fourth of the purchase price in the next 24 months. The Coolidge bull market was a remarkable phenomenon. The ruthlessness of its liquidation was, in its own way, equally remarkable.
