It's not a greed problem. Some people are driven to achieve. If that's greed, fine, call it greed. But others are satisfied to just get by, or subsist. They don't actively try to change anything about their situation. That's not caused by the "greed" of others. It's just their nature. So I agree, there will always be poverty because there will always be people who are satisfied to live in it. And by "satisfied" I don't mean happy, I mean not sufficiently motivated to change.
