Why do Credit card companies raise interest rates for no reason?

You can actually thank the government creating this credit card reform that was ped about 6 months and dose not take into effect for another 6 months giving the cc companies a year to jack interest rates up, cut limits "this hurts scores BTW" slash rewards, this is all to good paying customers. I think you can close your cards and continue to pay your balance at your Original apr. just wait until this category 4 hurricane of an economy blows over and once you get on your feet get serious to pay them off.
