Why?
If customers agree to those rates then I fail to see the problem.
When the customers have no other alternative, it's kind of like having a captive audience. The Government capped credit card rates, many of which exceeded 30% (with late fees and interest increases, many approached 50%, some even more. Why not cap ALL lending agencies??
Then there's one of my friends on Facebook that had a CC company seize his checking account, apparently without due process:
Capitol One has unjustly had lawyers from Ohio clear out my checking acct due to a clerical error they created, to the tune of $1766.68, plus all penalties for bounced checks for house payment, bike payment, bills, etc. "What's in YOUR wallet?"
