Student loan interest max

I don’t agree with student loan forgiveness, but the interest rate is smothering any chance to get out from under student loans for graduate degrees or higher/continued education. I’m a chiropractor that graduated with $216k in student loans, with interest it’s now almost $400k. Instead of 6.8+% interest on loans through Dept of Ed for the course of the loan, cap interest past a certain amount. There’s no incentive to pay over your minimum amount because you’re unlikely to be able to pay it off before it can be forgiven in 25 years.
