The reality is that cards can impose very high fees and businesses spread that cost out onto card AND cash payers. Card companies stipulate in the contract with the business that they CAN NOT charge extra for card transactions to cover the fees. That is why you see businesses offering discounts if you use cash.

The Visa/Mastercard cartel has too much power.
