I'd argue that greed is natural and that the economic system we've invented is more toxic. You can't fix greed, because greed is just a term "outsiders" use for people who act in their own self interest.

People should be greedy. There just needs to be a system in place that aligns the greed of individuals with utility for humanity. I can imagine such a system, so I'm pretty optimistic for the future.

I agree that some level of 'greed' is good just like other animal-level motivations (anger, lust, etc). The problem is that unchecked they can be consuming make for poor decisions in the long view. Plus, they don't need to be legislatively encouraged, as they will always be present in humans in strong form.
