millions upon millions... they make so much money in fact that they are expected to lose a certain amount on cards that will never be collected upon...because people will charge and charge and charge...part of your lack of understanding here is your generation...the younger generation that have bought huge homes beyond their means are aware they will never pay off their mortgages...the bank also know this...some generations will live in perpetual debt. Talk to some bank managers.Hmmm... I somehow doubt it. I'd immagine most of us just make sure we have the money in the bank before we charge anything to the card just to collect the 'rewards' and then set it up for free automatic payment from the checking account every month.
While I'm sure they make some money from the interest rate, I doubt it's that much.
Cards are the same.
