Yeah greed is actually a sub-disease as classified by some scientists.
I'm greedy as hell with my CPU but that's it. So I might have a small trace of this "sub-disease." Well what IF it were put in there with obesity? Walda think of that? People'd would be putting up money for a cure. That's why they don't categorize it.
Greed is good bad but read my page and it'll tell ya all you need to know about human behavior.

I don't think I'd examine the "logic" behind controlling the world while destroying it. ;p
Some people are greedy. It's that greed which drives one to reach the "top" of any control system. It is therefore inevitable that if someone is in control, they're probably greedy, and don't consider costs which aren't there own.
