Quite a few people from bear sterns went to jail recently for financial fraud. I'm pretty sure this type of fraud is all through out the financial world in our capitalistic culture. So I think we should outlaw all types of financial instruments such as speculation and hedge funds to prevent the oil nightmare from happening to another piece of critical infrastructure. I mean what if these super funds started buying up medical supplies and driving the price of them up?
It will happen to that or something else important to everyday life if we don't stop this behavior.
