could the 1929 crash of the stock market been prevented? How? Did the government do anything that could have caused the stock market to crash during 1929?
This would be a book or an extensive thesis or dissertation.
No one is going to do that homework here.
I can tell you that the gov screwed up the economy and the market and kept the US in Depression for raising taxes on individuals, and on business and created socialist programs that if not addressed properly could create sever financial issues for the the USA in the future.

Note: the first part (of the above program) is Bush bashing with some good arguments. The last part where they show the graphs and address actual projections of entitlements and not argue solely on politics is what I would pay attention to.
In addition during the late 1920's, the FED made a series of pre-Depression interest rate (increase) blunders just like it did in 1998-2000, and 2004-2006.
