> Greed is good for falcon, to go as far saying its the driving force for human progress is a little extreme! Greed has also forced third world nations to their breaking point.

I think you have noticed the quotation mark at the ends of the phrase. Perhaps the second part will explain what happens when greed applied incorrectly.

“But GREED, if directed correctly, is a most important driving force for human progress. Unbridled GREED can also be very destructive to human progress.”

"Ideas and concepts are a main driving force in human progress, and they are arguably the most important contribution of the United Nations"

Well, I certainly hope that GREED is not the only driving force for human progress.
