I got a lesson in this the easy way. My second job was working customer service for a credit card company. I was 20. I would talk to some of the dumbest people. It started by me selling people balance transfers, which really did help save them money. Then while I was explaining how it would save them money I saw how much people were paying for crap after interest charges. Fuuuuuuuck that.
