This level of community angst (there were a lot of people marching and a lot of occupied cities) is not so much about capitalism as a form of economic viability as it is about how criminality infiltrates capitalistic tendencies. There is probably “no” country more corrupt that our current empire here in the United States. That is the main issue. Not just corporate greed but its caustic effects in bribing Congress, the news media, the Executive branch of government, and the alienation of the majority of other countries against our lies, deceit, our government corrupting other peoples, the wars, and the torture, etc.
The 2010 Attac Bank Tribunal in Berlin was a civil society legal proceeding that decried the speculative business model: take excessive risks and burden taxpayers with the costs. Rating agencies should be public. Banks that are too big to fail are too big to exist and should be broken up. The government is complicit in bailing out banks and abandoning the real economy.
