Uh, yes they can.
Better for her not to have gotten in bed with credit card companies; lesson learned.
Now that she and millions have, the rewards I and millions of others that pay on time earned are on the chopping block because the people that got themselves into trouble with credit cards whined and moaned to Congress....
Let's see. Most credit cards are issued by banks. All banks enjoy certain monopoly benefits of being banks: they can create money out of thin air. In addition many banks have receieved huge taxpayer handouts, particularly some of the largest credit card issuers. Given this I believe that the industry needs to be regulated, perhaps more than most. The reason to grant banks the monopoly they have is not to make bankers rich, it is to make society work. 30% interest rates are not in societies best interest. For years, until bankers lobbied to have them repealed, many states had usury laws. In Connecticut until about 1982 no financial institution could charge more than 12% interest on a credit card. The banks seemed to be doing just fine, despite this restriction. When I was a kid 30% interest was associated with the mob. Now it's associated with JP Morgan Chase. Oh, I see I'm repeating myself.
I have never been late on any of my credit cards...all 27 of them. Then I started getting notices that they were lowing my limit or closing my cards(which destroys my credit when they lower or close an account)...so I say screw em if they are gonna destroy my credit by closing my accounts(that have never been late) then i am going to help them go bankrupt! I dont need credit anymore...
