Greed Is Good?

Read an interesting story from the BBC about the founder of the the Bank Of America. The economic disaster that was created from a "greed is good" mentality, must have him spinning in his grave. Greed has been around as long as the concept of personal property has existed, but it became a cultural phenomenon in the US, which, like a lot US "culture", has been exported to the rest of the world. I hope that some lessons have been learned but I don't have that much faith in human nature.
