Are you really going to take the position that increasing the discount rate on speculative loans caused the Depression? I presume that's what you mean by "attack the Stock Market - tell me if you mean something else.
1929 and the Great Depression are two different things, though one was the first major event that led to the other, but read my post again. The mere mention on numerous occasions that the government was going to attack the market greatly increased speculative behavior, and then the final act that led to the Crash was an act of government. They warned about it frequently and then they did it.
