The fact that greed is holding the human race back from maximizing it's potential is such a shame.

I would say that on net “greed” has helped humanity far more than has held it back.
(But I don’t know the context in which you are making this statement)

I agree with you.
In this context, I am talking about a greed where you attack others that have a better idea so you can survive.
Imagine you create a free energy device and I am a trilionaire that owns multiple oil companies.
Your invention threatens my companies, so I will kill you.
That's the type of greed I'm talking about, but you can call it anything you want
That makes more sense and I’d probably agree then.
This can take so many forms. “Make work” regulations and rules that prevent innovation ultimately hold us back. I heard of one case where a local plumbers group fought to get local building ordinance to require copper pipes which are much more expensive and labor intensive than modern PEX fittings which are basically plug and play.
