Businesses raise prices to account for interchange fees. So they are essentially is paid by the consumer. If we outlawed rewards credit cards (by capping interchange fees), everything would likely be slightly cheaper.

Agreed, which makes the picture even worse for those low income people. Even poor people are guaranteed to occasionally pay the "rich person tax" included in the prices of some of the products and services. At least until some AI pricing starts changing the price real-time based on the buyer's estimated wealth (sort of already real).

Not from a bank's perspective. Only in the sense that prices are higher between the seller and buyer.

I don't agree on the second point as a blanket statement. When Epic game store lowered its fee not a single game got cheaper for the buyers.

Outlaw rewards credit cards? Or make it compulsory that the true cost of a specific credit card is revealed to the merchant who has the right to absorb or pass on, in a line item, that cost to that specific consumer?

If I know I'm paying for my own rewards, I'd choose a card that keeps more money in my pocket. I'd go as low as the PITA factor of cash.

It's not clear to me what the net benefit is of a credit card over a debit card.

But for sure the confusion ensuing from allowing debit cards to be charged as credit cards should be illegal. The merchant account providers are probably the ones reaping the free money on the racket.

Credit is the POS default, for whatever reason. Not all POS are the same. e.g. US Post Office consistently knows if I am using a debit card, and it prompts for a PIN when I do. Every restaurant, bar, service does not ask for PIN, and the handful of merchants I've inquired with say their debit card fees changed by the merchant account providers are the same as credit. Scammy.

At least in Colorado it's legal for businesses regardless of the TOS contract with a merchant account supplier to pass on the transaction and processing fees of credit cards. It's not legal to pass on cost/fees for debit cards, ACH, or cash.
