A quick web search turns up legislative efforts in both House and Senate to cap credit card debt interest rate at 10%. The House bill sponsored by Reps. AOC and Anna Paulina Luna, the Senate bill by Sens. Sanders and Hawley. I understand these to be well-intentioned.
Expect there to be several unintended consequences of these efforts. The cancellation of many outstanding credit cards, especially those held by individuals thought to be other-than-excellent credit risks. A lower cap on amount borrowed would be logical too. A recessionary reduction in spending. And more reliance on so-called "paycheck loans" and loans against car titles.
The 10% cap may still be a good regulation but fully understanding the consequences before plunging ahead with it seems indicated.
