I dont think the emotion of greed can be kept in check. Maybe the action of wealth hoarding.
You're right Gene, the fallout from greed?
I really feel sorry for people that are obsessed with making money. It's like there is something wrong with their brain like an obsessive compuslive need to be richer than everyone else.
I actually heard something about this recently. Ohh I'll need to do some research. But it was as you say, some kind of disorder.
