What, for you, is the threshold of personal financial debt?

What is your comfort level of amounts outstanding from month to month on credit cards especially? Do you carry a credit card balance from month to month or do you tighten your belt if necessary and just not purchase on credit until your existing balances are fully paid?

Please discuss this at length if you wish, what your philosophy is. For instance, I have heard it said that the generation now in their early adult life have the attitude that get as much as you can while you can because the thing (world economic system) is going broke and it won’t matter anyhow in a short while.
