The Best and Worst Credit Cards by CNNMoney

Suprise, surprise... " Consumers who used the MasterCard and Visa bank cards through JPMorgan Chase, Bank of America, Citibank, Capital One, and HSBC, complained that they were assessed unfair late fees or experienced unexpected interest-rate increases. "

Twenty-eight percent of cardholders surveyed who pay the highest interest rates (interest of more than 25 percent) reported that their rate increase was due to a universal default clause. Cards that employ a universal default allow issuers to increase rates if a consumer makes late payments on other accounts, such as car loans, mortgages, or other credit cards

My question is where are the regulators or does anyone really care?
