It just seems like a scam to me. We buy things with credit cards to get the points and each transaction costs the merchant money. The merchant raises their prices to cover transaction fees, so now you're not really getting points - you're paying hidden fees that get some rewards points for (but not enough). The real scam is that it's such a monopoly now (oligopoly?) that if you don't pay with a credit card then you're losing out - you're paying inflated prices but not getting the reward points.

Now, some people have to pay with credit cards, but that shouldn't be the norm. If you're perpetually one month (ie, one payment) behind on bills, etc, then credit card makes sense, but that should be an edge case - just need to save for a month and then you're good. (yes, lots of shoulds and wishful thinking there, I know, read the next paragraph).

If you fall more than a month behind on payments, the you're paying some 20% interest, which is likely going to destroy you anyways. So living "a month behind", while maybe the reality for many is likely to get way worse before it gets better.

I will acknowledge that CC companies provide things like insurance and liability protection. I think that if governments and/or banks could provide this, there would be no good reason to use a credit card beyond the odd big purchase. And realistically, some international transactions, as well, since it will take a long time before all our payment systems are integrated to that degree.
