The other replies are correct but to explain the credit “game”, using credit cards is the easiest way to get started showing banks how responsible you are about paying back credit. For large purchases which most people will need credit for, e.g. new car or house, banks want you to have a good record as a borrower. As to the overspending issue, that is indeed a problem that many have. I think credit issuers mostly want to walk a very fine line, accepting that some really won’t be able to repay their debts while others can and simply spend more of what they can but might not if they weren’t using credit.
