Direct price controls like that, are generally a bad idea. Often, unintended consequences make the underlying problem worse.

For drug prices, most are created with substantial government funded research. The government could leverage that into a major patent ownership stake, then immediately license the drug for generic production.

For child care, the government could give a monthly stipend to all parents. Parents could then decide, use it for child care, or quit/cut hours to care for your kid yourself.

I'm not sure about interest rate limits; That might work. But 10% is kinda low. Maybe someplace between 15-20%. And credit cards aren't even the worst offenders. Pay day loans are much worse, with rates over 200% sometimes.
