Perhaps in the long term, but not necessarily in the short term. The process of medical school accreditation is separate from the number of residency slots, increasing program sizes, or creating new residency programs.

There are still MDs who go unmatched into programs and the job market for general practice without being board certified is very limited. I think it’s pretty illogical that in many states midlevels (usually NPs) can gain fully independent practice (FPA) shortly after graduating while physicians cannot (licenses require 1-2 yrs of residency training before you qualify for licensure).
A lot of this comes down to lobbying, unfortunately.

This reads like someone who isn’t familiar with how physicians are trained.
The number of residency slots is effectively stipulated by the Medicare budget. There are more and more medical school grads who go unmatched to postgraduate training because there simply aren’t enough spots.

The answer to our healthcare woes is not to relax medical school standards and physician licensing standards.

The increasing degree burden you’re speaking of has nothing to do with physicians. Non physician provider education has been increasingly bloated by degree inflation for the sake of monetary gain on the part of the educational system. An NP, for example, used to require many years of bedside nursing followed by a masters degree. Now, you have for profit universities churning out new grad nurses who have gone straight from undergrad into all online “doctoral” NP program that allows them to practice unsupervised in some states, while having fewer than 500 clinical hours.
