It's a prisoner's dilemma. If we collectively switched to a payment system with lower transaction costs, we would all be better off. But as an individual, it is in your best interest to use the credit card with the highest rewards program, because you have to pay that extra 3% either way.

Agree, and specifically for prisoner's dilemma/tragedy of the commons scenarios we have the option of regulation, which corporate propaganda has labeled as "government intervention is always bad".

And we also taught our children to be ethical and aim to do good, even in school, which helped.
