Of course the banks are up in arms about any legislation that would turn off the usury spigot they've milked for decades. Ann Logue at Popdose points out just one example:

...my credit card limit is $20,000. I could use the card to fly first class to Paris and go on a spree at Le Bon Marche yet pay no interest if I paid it off in full the first month it was due. But take $140 from an ATM and hold the balance for 20 days or so, and the total fees and interest work out to about $24, an annual interest rate of 208%.

Another crazy practice is late fees: I've received a credit card statement showing my payment as posted (they got my money in time to print it on my paper statement) but because they posted it one day after their "due date" they tried to charge me $29.00 in late fees. I called and complained (which works more often than you might think, do try it) and they reversed it, but how many $29.00 payments do you think got added to their balance sheets this year from people "afraid" to call a creditor?

Obama's bill does not go far enough, and doesn't start soon enough (one year for most of its provisions IF the Senate passes it) but it's a start.
