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?

> Greedy people put the desire for more money above the welfare of the business

In my experience, it's much simpler.

People are greedy if they make things I want cost more.

> Approximately everybody would like more 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.
