Well, I suppose it depends what you use the card for. If it is to buy things that you cannot afford and run up debt, then it might be a good idea to just cut it up or cancel it.
I, as I am lucky enough to be able to do, you just use it because it is a safe way of buying things (especially online) and you can pay it all off every month then hang on to it.

I really don't like the idea of having a credit card but the issue you raised is really important
