Wow. Capitalism didn't fail, greedy men created a Ponzi scheme which failed.
Leveraged investing in phantoms, relying upon an ever rising housing market, collapsing.
It makes very clear what WorldCom and Enron also made clear which is unregulated capitalism is doomed to failure not because the system is faulty but because it is run by men quite suseptible to greed.
In order to protect itself the system must be regulated to protect the society from the very human trait of greed in the few.
