I seem to have edited my post while you were answering a point I later took out because it didn't seem relevant to the main point (which is that I don't think anyone has introduced basic income yet).
However, I don't believe in your analysis of the banking crisis, either. You seem to have missed out a lot of other reasons. From wikipedia:
> In its "Declaration of the Summit on Financial Markets and the World Economy," dated 15 November 2008, leaders of the Group of 20 cited the following causes:
During a period of strong global growth, growing capital flows, and prolonged stability earlier this decade, market participants sought higher yields without an adequate appreciation of the risks and failed to exercise proper due diligence. At the same time, weak underwriting standards, unsound risk management practices, increasingly complex and opaque financial products, and consequent excessive leverage combined to create vulnerabilities in the system. Policy-makers, regulators and supervisors, in some advanced countries, did not adequately appreciate and address the risks building up in financial markets, keep pace with financial innovation, or take into account the systemic ramifications of domestic regulatory actions.
i.e. Though it was also a failure of other things, it was by large part a failure of corporate risk assessment and lack of regulation.
