I think the Grandfather was making a different point. That because rewards cards = higher interchange fee for the merchant, this results in the merchant increasing fees on everyone (the payment networks prohibit charging a higher fee to only those paying with a credit card).
>>>The money extracted by the credit card companies and Visa causes merchants to raise prices for everyone regardless of whether they have a rewards card or use a credit card at all.
>>>This creates in effect a massive money transfer from the poor, who do not use rewards cards, to the rich consumers who do.
The poor/low-FICO scorers are either A) not getting accepted into credit card programs, B) paying higher interest rates, or C)not able to make their payments in full each month.
Compared to another individual that can put all their purchases on a rewards card and pay off their balance every month.
The pricing point isn’t that complicated either. Nearly every business accepts credit card and can’t avoid the higher credit card fees that pay out to reward programs.
