To scare the lawmakers, themselves large owners of the very banks and stocks that they are supposed to be regulating, a financial Weapon of Mass Destruction was put to their head and they acquiesced.
As the inventor of the continuous double-action, market-making technology (VST tech. US pat. no. 5950176) that is referenced 132 times by program trading and HFT patents since 1996, I can tell you that Goldman, JP Morgan and the gang simply pulled the ‘buys’ from their computer trading programs and manufactured a crash. And when the coast was clear, and it was clear the politicians were not going to vote for anything that would break up the ‘too big to fail’ banks; all the ’sells’ were pulled from the computers and the market roared back. --Max Keiser quoted in BigPic
