People get way to caught up in the allure of the credit card. Too many young kids these days look at the credit card and get way to happy that they have so much money to spend. Hell, I knew quite a few friends in college who had two or three maxed out credit cards. Most people do not realize the fault of a credit card until it is too late. Furthermore, there are those who use it thinking mommy and daddy will bail them out. What I am trying to say is that I agree with the previous posts and that is those who tend to be sensible about money expenditures use debit cards.
People who want quick money now, and lots of it go for the credit card and then find themselves suffering from it's evil later on when the bills come rolling. Now don't get me wrong, the credit card is a very useful tool in times of emergency, but many out there just find it way to hard to resist the urge to spend so much cash. Everytime I open up my wallet I can hear it say spend me and yet I use that little thing called a conscience (yes i do have one despite popular belief) to refrain.
