Should young adults have credit cards?

For me I think that would depend on the person you are giving a credit card to. Having a credit card is a big responsibility you know, you just don't splurge on things and buy useless items with it or else the bills are gonna pile up at you. It is a good way to test on how you can be responsible money-wise. So for me that is ok, as long he/she is responsible enough to have one.

While it does encourage responsability it is too easy for it to get out of hand and end up buried under. Its easy to loose track of how much is on there and should you miss a payment the interest rate shoots up along with all the fees they add on. For most young people it'd get out of hand before they ever learned how to use it.
