With all due respect, where are you getting this information? As I think we all agree, we don't have all the facts, so I am surprised that you feel comfortable making these statements so unequivocally, especially in light of your earlier post in which you agreed that we don't have all the facts.

As for causing Chase losses, remember that it doesn't take much to fall into that category, as its profit margin on customers who don't carry balances is pretty small (also remember that Visa/MC/Amex take a percentage, as do other companies for whom Chase runs affinity programs). If you wisely use your CC's in a way that maximizes your rewards and takes advantage of each CC's strengths while not using it for anything that it is weak in (and select CC's that lead in their respective rewards categories), you are a financially sophisticated person, which probably makes you an unprofitable credit card customer.
