The only economic benefit I see with credits are the rewards/protections it provides for everyday purchases. Here in the states, we don't have a cap on interchange rates for merchants. This trickles down into benefits (For example on my Amex card)
- 1 year extra warranty on top of my purchases, with return protection if the merchant
- Points / 'Cash Back' (much higher multiplier) that can be used to purchase airline tickets or gift cards
This is essentially free money and protections if you use the credit card and fully pay it off, but obviously, most Americans carry balances over and the interest charges basically negate any rewards.
