You’re correct that PAs, FNPs and CRNAs have less training than their comparable physician counterparts, but they too are saddled with lots of debt.
Physicians made the mistake decades ago allowing 3rd parties to govern what they get reimbursed for services.

The dentists have been much smarter. 3rd parties don’t dictate to dentists what they get reimbursed for their work (for the most part)
