you are unique then since I know a number of people over the years who did that and got their cards canceled
and you are also wrong about how much they make off of fees; its not a PATCH on what they get for a sizable balance carried over
And I have heard from those who work in banks credit card sessions and your claims are frankly laughable
Cash back and rewards are a PITTANCE compared to carrying sizable balances as regards revenue.
they consider employing collectors just a cost of doing business - it is all very carefully calculated and your view of them is very naive
Perhaps my bank never cancelled my card because I worked for a major bank and credit card issuer for over 30 years. Of course banks make money on interest they charge on balances. I never said otherwise. What I said was they make money off of you whether you pay your balance or not because they get fees from retailers. Which is a true statement proven by the fact that American Express required customers to pay their entire balance every single month for many years. Credit cards issuers charge customers between 1.5% and 3.5% for every transaction.
Did you know that only about 40% of card holders carry a balance on their credit cards? Banks do no want you running up high balances on your cards because then you can't use them to charge things. They want you to use your cards as frequently as possible. The card is an instrument to get transaction fees, which are small, but when you have say, 1 billion card holders using their cards 20 times per month that is 20 billion transaction fees per month. It is big money.
I will guarantee you if you run up a high balance on your card and fail to pay on time you credit card company will cancel your card faster than if you pay it off every month. And by the way, there is a difference between not using your card and paying off the balance every month.
