Incorrect. Greed and progress benefit a privileged minority. Tell the impoverished of Africa, Latin America and Asia that greed is good. Tell the people rotting in urban ghettos, in prisons, tell those who have lost fingers or limbs to the unstoppable machine of institutional greed, that their sacrifices were necessary. I would rather have stagnation than to leave the world as unequal a place (or moreso) as I entered it.
Perhaps you didn't read that whole "can be better" part. It's not always and not for everybody. Unfortunately, I can't solve poverty and world hunger. Perhaps you don't understand, but neither can communism. There are limited amounts of resources and money. Even if you could allocate the resources evenly (which you can't) nobody would have enough to live on.
