People who "pay off [their] credit cards in full each and every month" bring loss to the credit card companies. For this loss other credit card users must pay :)
True, but they still benefit from me using the card over using cash, because they get a cut from the vendor on the sale.

Actually, you pay a little. When my kids were younger, I used to carry a small balance on my card. They got older, my wife went to work, I changed cards to one with better terms. I never carry a balance, my credit rating took a hit. It's still good, but they dinged me.
Are you sure that CC companies loose when one pays off the card in full every month? It is hard to imagine that with the 3% of the charges they get from retailers, that they would loose - it shouldn't cost very much to service an account these days.
I would be willing to bet that card users are paying more for the costs of others' defaults, rather than for the people not financing balances.
