Utter nonsense. Greed begets greed. Do what is right.
Nonsense. When company A becomes too greedy and abusive of customers, it creates an opening for company B, which gives company A a major incentive to not get too greedy.
I might suggest you check out the “invisible hand” as described so well by Adam Smith in 1776. We don’t depend on the benevolence or ethics of businessmen to protect customers, we depend on their greed. Or enlightened self-interest, if you prefer that term. Either way, it means the same thing.
