Tackling credit card interest rates is a legitimate policy goal worth pursuing. Here's the thing though—if we cap rates at 10%, we're likely looking at a massive wave of card cancellations. Why? Simple math. Credit card companies operate on thin margins outside of interest income. Start cutting that off and they'll shed high-risk customers like there's no tomorrow. That means millions could suddenly lose access to credit. The unintended consequences matter just as much as the good intentions. It's the classic policy trap: fix one problem, create two others.
