"they are "punishing" people that don't make them money."
Not really true.
Every purchase on a credit card, even if there is no balance on which interest is earned, nets the card company a percentage right off the top of the sales price of the item.
On Visa and Master Card IIRC it's about 2%, Amex is far higher, which is why a lot of merchants have told Amex to go stuff themselves.
What the card companies are doing is looking to their SAFE customers to bail them out for the failures of the unsafe customers, who were only customers because of horrid lending models and a Satan may care attitude towards accumulated risk by the card companies themselves.
What they're really saying is... Well, we screwed up by trusting those deadbeat people, but it's not our fault. It's really the fault of these other dead beat people, the ones who haven't cost us anything, but they sure haven't lined our pockets for us!"
Oh, and this MIGHT be a way around getting nailed by a drop in credit score from a card company closing your card unilaterally, or you closing it, which drops your total available credit and raises your debt to available credit ratio...
I have credit cards with two credit unions.
One has a fairly decent credit limit, the other one, however, still has the original $2K limit that it had in 1988 when I first got it.
Say I decide to tell chase to go stuff themselves. My Chase card has a $10K limit.
I call my credit union and tell them "I'm going to be canceling my Chase card after I get off the phone with you, but I don't want to destroy my credit score. I want to raise my credit limit on my credit union card to $12k."
I'm thinking that if you are in good with your credit union, have a good track record with them, that should be a pretty decent way of covering your bases.
