Greed

Greed, according to the Merriam-Webster dictionary, is "a selfish and excessive desire for more of something than is needed".

In Christianity, it is one of the Sins — such desires being seen as turning the heart away from God — and has been roundly condemned in most historical codes of morals; not without justification, as the greed of kings and other monarchic rulers could be the driving force behind endless war and political infighting.

However, in more recent years, greed has been re-evaluated and now is seen by a significant number as being a positive force in a capitalist economy, as a greedy person, by enriching himself, increases economic activity and helps everyone around him ("a rising tide lifts all boats").

...except when it fucks everyone over if appropriate laws haven't been levied to constrain it.

Quotes
The point is, ladies and gentleman, that greed — for lack of a better word — is good. Greed is right. Greed works.

We wants it, we needs it. Must have the precious. They stole it from us. Sneaky little hobbitses. Wicked, tricksy, false!
