If the banks lose money, why would they raise anyone's credit limit for active spending (which is what many do)?

And, getting back to the earlier discussion, if the banks thought a credit limit should be the limit for a month's spending on a card, they could easily program it in. Simply don't make any more credit available, regardless of payments, until after the monthly statement closes.
