I'm not of the opinion that greed alone is bad. Without it life would be miserable.
But there does seem to be a type of short sighted, self serving greed that I think is without merit.

I can get $100 by working for a few hours, or I can get $100 by robbing someone. Both actions are motivated by greed, but one moves the world forward, and one moves the world backwards.

Technically achievable, yes. Likely achievable, probably not. As long as there are finite resources, there will be conflicts, from the individual level, all the way up to the level of nations.
