Greed is not a recent discovery. The desire to produce more with less is not new. Rather than looking for "villains" it might be wiser to look at the realities of the "world market" and try to figure out how to deal with it.
There was a time that when we wanted a car, we looked to MI, when we wanted steel, we looked to PA, when we wanted corn, we looked to KS - cattle TX, jazz LA, investment NY, and so on. It's the same today except the states have been changed to nations.
It really isn't a case of "good" or a case of "bad" - it's just a case of "is".
Greed is old. Greed is good because without the desire for more there is no motivation to advance, change, learn or adapt.
But corporations have taken greed and enhanced it with accountants, lawyers, money and access to people & places the average individual or small business does not have access to spreading & perpetuating greed on an industrial scale.
