The problem is that exploitation of anyone and everyone you can has been normalized and glorified in our culture.
We could just all agree that exploitation of others is wrong and unacceptable and severely punish those that try to exploit vulnerable people. But no, defauding Granny for her entire retirement is acceptable behavior now.
It's not just "acceptable behavior", it is literally taught as the thing to strive for in business programs and obsessed over in weekly meetings and the primary way to get on magazine covers.
