Apologies, I'll try again. At both ends of the human spectrum you have people who are so basic human life means nothing to them. In both respects these people want power over others. I suggest the least intelligent are the serial killer types but the most dangerous are the rich and powerful. Wiki commodities brokers.
Fair enough. I think people are people and good and evil are probably normally distributed between the poor and the wealthy more or less. There are certainly bad people at both ends.
I'm familiar with what commodities brokers are and don't see anything wrong with it. I'm quite happy for the existence of modern financial markets.
