Approximately everybody would like more money.
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.

In my experience, it's much simpler.
People are greedy if they make things I want cost more.
I think there's one more factor that is crucially important — greedy people lack long-term vision, and care a lot more about money now than they do about potentially much more money in the future.
I suppose it's kind of interesting that you could measure greed as an unusually high discount rate for the time value of money?
