Not mentioned: how rewards/cash back cards are a scheme to transfer wealth from the poor to the rich. It happens not just from the fees charged to merchants, but also through interest being charged to people who can't or won't pay off their credit cards each month. Merchant fees are particularly insidious, since not many stores offer discounts for cash, or charge for using a card, so those fees are hidden in inflated prices that everyone pays, regardless of payment method.
