If big businesses knew they had NO guarantee of bailouts from a central government.. I think their business practices would be a little more conservative. (Read Mortgage scandal here)
If a business does fail, there is always bankruptcy court, where they can revamp their business model to stay in business. If that doesn't work, then there are always competitors that will step in and fill the void.
Use the free market system as it should be used and we will all be better off.
Oh yea, and Bernie sucks.
