The deregulation of the financial sector directly led to the Great Recession in 2008, just as it did in 1929. Allowing banks to invest people's assets in complex processes that they themselves, let alone the "informed consumer" don't understand is horribly irresponsible and erroneous. It's human nature to forget the lessons of history, and it's the government's job to insure for the welfare of its citizens. Therefore we cannot use antiquated economic philosophy based on 19th century models. Free markets are good, to a point where the government must check the influence of large multinationals.
