"From 1921 to 1929 the Federal Reserve pulled the same trick that they had before, increasing the money supply up to 62%, seting us up for the longest economic slump in modern world hisory. They addd to their system a new kind of loan in the stock market called a margin loan, allowing a person to buy a stock for only 10% of its cost. The other 90% was covered by the broker. The cluase being the loans could be called in at any time and had to be paid 24 hours from that time. In the middle of 1929 J.D. Rockefeller, Bernard Burack and other insiders secretly pulled out of the market. On Oct 24 they called in the loans in, in massive numbers. This caused over 16,000 banks to collapse; they were able to take control of almost all. Then they dropped the money supply to a record low, resulting in one third of America to be unemployed, this is known today as the "Great Depression".
