Theft.
Credit card companies love it when you go into debt, because it means they can keep charging you more and more, until the point where they possess your house. Poorer income families very likely don't own their own home, therefore the credit card companies don't get their money if the people default on payment. With no house and no income, nobody can get a penny from you. It seems that the companies are just jumping that and going into the straight theft. Why should we allow that?
