This is a silly discussion, but it is a slow day so I'll play along for a while.
I have 6 open MC/Visa accounts currently with a combined available credit limit over 6 figures. They all have zero balances, except one that I use for convenience and travel which has a current balance of about $450 and is paid in full every month. No, I don't need all of that available credit, but it is nice to know it is there if I ever do, and leaving them open only enhances my credit score.
That said, I have carried balances at times for a variety of reasons.
1) To ease short-term cash flow obstacles (which is the circumstance Slick appears to have).
2) For emergencies
3) To help family members (such as the time I bought a car with a credit card for my brother - and spread the cost over 6 months rather than taking the money from my savings account).
4) To survive a period of unemployment (okay, that was a scary one, but the alternative was to lose the house and/or car) and I made it through without a single late payment on any obligation.
5) To buy a car that was too old to get attractive auto financing.
The interest rate on my primary card is 7.99% with no annual fee and bonus reward points. NONE of my cards has a rate above 12.99%. I checked my credit union and their rates for an unsecured personal loan START at 13.99% and go up from there.
So somebody is going to have to do a better job of convincing me why I'm being so stupid.
I'll say it again, credit cards aren't the problem - lack of disipline and bad choices are.
