ABC News reports that a new law regarding credit card fee limits will be passing soon (Monday if all goes well). The law limits how quickly/easily credit card companies can raise their rates. It won't let the government cap the rates, but it will force companies to make it clearer to their users what there rates/limits will be.
ABC states that, "Credit card consumers will soon see expanded protections, fewer fees and more clarity thanks to a so-called Credit Cardholders' Bill of Rights that is working its way through Congress. The Senate passed its version of legislation by a 90-5 vote this afternoon and the House has already approved its own version."
Again, easiest way to keep the companies from taking advantage of us? Stop using them. Seriously.
