The last recession was largely caused by private and government institutions that are "Too Big to Fail". Large banks and investment banks that are so large that their failure would damage the US Economy should not be allowed to exist. Big government subsidized organizations like Freddy Mac and Fanny Mae also fit this category.
These are monopolistic organizations that could probably be broken up by current law but are not. New legislation should be enacted to address the banking and finance institutions that have grow too large and now are a constant danger to our economy. Any organization whose failure is large enough to damage our economy needs to be broken down to reduce its monopolistic powers and to limit its impact on our economy.
