If you pay off the balance each month, then I applaud you. As I said, most people don't, and many people have serious debt that adds up. I still don't see your benefit in having a cc.
You're saying "most people" don't pay off their card every month, but then saying you don't see the benefit to those of us who have told you repeatedly that we do pay it off every month.
If you
don't pay it off every month, I totally agree that it's a bad thing.
If you
do pay it off every month, I totally disagree with you that there is no benefit.
1. I earn really good cash-back bonuses.
2. I only pay one bill per month instead of several (utilities, doctors, etc.).
3. Balancing my check-book is easy because there aren't tons of debits in it, just a handful.
4. I never have to worry about forgetting to write down a debit-card use, thus making me think I have more money in my account than I do and getting overdrawn.
5. I never have to think "do I have the money in the account
right now" when I make a purchase.
If you don't feel comfortable using a credit card, that's totally fine. But don't make blanket statements that all those of us who do so - and do so responsibly, and have done so for a really long time with no problems and only benefits - are making a bad decision. It works for us. We're not saying everyone should do it. Only that if you do it right, it's a good thing.
It's all about being honest with yourself about what you're capable of doing. If you will not be disciplined enough to only use the card for things you know you can pay for at the end of the month, don't do it. If you will sometimes forget to pay your bill on time so you will end up paying interest after all, don't do it.
