Deep Question of the Day

This one is not about philosophy, but annoyance. Why is it every time I finally pay off a credit card, I immediately get an e-mail telling me about "more ways to use your credit card" or have my credit limit automatically raised? The credit companies more and more these days act like drug dealers. "Oh, you're trying to get clean? How about one more free sample?"

And I say that as a bank employee. When I pay down my car loan, the bank doesn't try to get me to buy a boat on loan!
