"Rate hikes and late fee traps have to end. No more fine print, no more confusing terms and conditions", said President Obama last week when advocating another big-government solution -- this time to evils committed by credit-card companies.

Credit cards are a demagogue's dream come true. What better way to win public affection than to rail against banks for their harsh terms? In the politicians' morality play, creditors are the villains and debtors their helpless victims.

A little context first: No one has a natural right to a credit card. Someone has to be willing to undertake the risk in issuing it. Banks issue cards in their quest for profits. Nothing wrong with that.

Think about what a credit card is. It's convenient access to unsecured loans, permitting consumers to buy things large and small -- not to mention emergency services -- without cash. Pay the bill promptly, and you enjoy a fantastic service for virtually nothing. If circumstances prevent you from paying the bill in full, you can set your own payment schedule, realizing there is a minimum payment and that you will be charged interest on the unpaid balance. No surprise there.

To appreciate credit cards, it is worth recalling that before they came along, people got personal loans from banks, finance companies, pawnshops and loan sharks. Such loans were less convenient, and repayment was less flexible. Some people bought things on layaway, which meant they didn't take the goods home until they were paid for. Loan sharks sometimes broke people's legs.

Credit cards didn't create consumer debt -- they are merely a superior alternative to older methods.

As President Obama and other politicians demagogue this issue, keep two things in mind: Life would be more difficult without credit cards, and banks don't have to keep issuing them. Be careful what you ask for. Continued...
