This is disinformation and has been covered many times on FR. I have accounts with all those issuers and the minimum payments didn't double; most went up very modestly if at all. My new minimum payments tend to be about 1.5% of the balance. Only high-interest rate balances minimum payments are anything like 4%.
One of them went up only 5 bucks, the other, I think was 3 bucks.
I agree with that.. I have Bank of America and mine jumped from 53/mo to 129/mo.. of course I was paying off more than the minimum anyways and as a percent I'm sad to say that's not very much still... no where near 4%. That darn debt I racked up in College.. gotta pay for all that fun now.
