Political corruption can only be challenged by enforcing regulatory laws against banks, big pharma, big agriculture, big military industrial complex. Failure to regulate and the repeal of Glass-Steagall allowed banks to offer easy money mortgages in such quantities as to push the prices of houses upward. This artificial price rise was unsustainable.
As long as the government fails to protect the people from the bankers and other powerful interest groups, America will decline as a nation. The corruption of the libertarians is well known, as they supported all this deregulation of banking, both here and in the UK, where banking has even less regulation than on Wall Street.
The square mile is the City of London financial district, which allows speculation in futures contracts, with oil and other commodities to run wild. Where else can these speculators profit better than through a housing bubble?
The UK has had 4 housing bubbles in 40 years. And Wall Street is learning their way of operation all too well.
Even the pink slime found in McDonalds and other fast food burgers is a result of deregulation.
Until politicians become more powerful than bankers and corporations, all is lost.
