What are everyone’s thoughts on the potential 10% cap on credit card interest?

Without politics being involved, what are everyone’s thoughts on the interest cap being 10%? What are some of your predictions on what will change between banks, rewards, acceptances, etc?

I believe that most card reward programs will likely fade, unless you pay an annual fee. Including lounge access, credits, cashback, points, miles, etc. I believe it could be a good outlook for Americans stuck in major financial debt, but I feel the rewards system is in MAJOR jeopardy should this bill be passed.
