Credit Card Interest

I think it is just horrible how some credit card companies take advantage of people when they can't pay their bill off every month. They like to hike it so high that a person can't seem to get unburied from their debt. I have learned that it is important to pay off the amount due every month and do not have to deal with stuff like this but I do know of some people who deal with it every month and my heart goes out to them. I think it's wrong to charge so much, why wouldn't they want to help people out a little so that they could get their debt under control.
