This is wrong.

It's medical students, not residents, who take research years, and that's only for extremely competitive specialties.

The lack of doctors, as it has always been, is because of the shortage of residency spots.

That cannot be addressed without Congress reversing 50+ years of neoliberalism trends and political failure and refusal to invest in public services and/or a communist revolution. Good luck fixing that.

Congress should end the AMA guild's chokehold on linking "Medicare" to medical training at all. It's a complete grift.
