People don’t pay, because broke people got credit card and never paid it more than those who actually do

I’d like to see the numbers because you have a lot of people who use the card and pay it off every month, so the transaction/merchant fees are profit and there is virtually no cost aside from the account maintenance (running the website, sending bills, etc.), which should be minimal. Then you have a lot of people who use it (generating the same revenue from merchant fees) plus they pay interest because they only make a minimum payment or something. Then you have the people who just don’t pay at all (though they still generate the revenue on their initial purchases at least). 

It just seems unfathomable that these people outnumber the “pay off every month” AND “pay minimum every month” by such a large amount that the bank is actually losing money on the card.
