Why u should not owe money on a credit card

Lengthen of time it will take to pay off $3000 of outstanding credit card debt at 18% interest rate by making only the minimum payments: 14 years, 9 months. Amount you will pay in interest: $2350. In othet words, if you owe this money when your kid is born, your kid would be going to university next year and you should be able to pay one semester tuition... Wonder why credit card companies are good buys even when times are bad?
