Greedy people put the desire for more money above the welfare of the business, themselves, and other. Greedy people literally put their desire for more personal wealth above the very lives of others.
Greed/not greed is a very fair way of putting it. One can operate a business that requires profit without wanting to destroy everyone and everything that stands in the way of more money.
I suppose it's kind of interesting that you could measure greed as an unusually high discount rate for the time value of money?
For me (and many others), money is a means to an end. I don’t want money per se, I want housing and food and things that money can buy.
But for a few, money is the goal. They want money for the sake of more money. They don’t need more. That’s greed.
In my experience, it's much simpler.
People are greedy if they make things I want cost more.
