I think when you have excess of stuff and refuse to share.

Why I’m one of the top zapper of sats on SN I can’t criticize buffet and not break bread with the stackers!!

I still remember my dad telling me (born in a literal log cabin, dirt poor) some of the most greedy people I have ever met were poor. Greed isn't about how much money you have.

Always stuck with me. Some of the generous people I have ever met were very wealthy too. I know plenty of generous people that are not wealthy. People often surprise you. What you expect is often wrong if you are willing to accept it.

The desire for something you do not have. It's something pretty much every human has as well. Not just those with wealth. Capitalism has incentives that take that into account and use it to build wealth for all of society.
