molloch is the personnified logic of someone doing something selfish for their personnal gain, but when everyone does it, everybody loses. In this case the belief that one can churn rewards and come out on top with using a credit card but the result is that ALL prices are jacked by 3%, nullifying any apparent rewards, at best you can claw back a little bit of this corporate tax. But here's the kicker, if you don't have a credit card, the price is also jacked, because credit card company do not allow passing the fee to end customer. So non-credit card user, still pay the 3% tax, it just gets pocketed by the vendor. I cannot overstate how evil credit card company are. When I am Earth dictator, all credit card employees will spend time getting acquainted with a brick wall
