I agree with you. I'm just saying, most expansion efforts are pushing for most new residencies to be in FP, peds, and IM. If we have enough physicians trained in primary care fields, some of them will have to start taking jobs farther out as markets saturate. Once people can actually find physicians that are willing to take them due to us having enough PCP docs available, the nurses won't be able to push their BS excuse of "not enough providers" anymore, and will have to take a stand on pushing for expanded scope based on their training and experience, which is something that is much less likely to fly.
If you think we don't have a shortage of primary care physicians, try finding a FM or IM physician to see you in the next week. There was one PCP in my entire county that was taking new patients- every other provider that was taking people on was an NP or PA. If you want to see a physician for primary urgent primary care services (being sick or whatever), it's pretty damn hard to arrange.
If we've got way more PCP residency positions (due to a residency expansion bill) than we have fellowship positions for those IM grads to match into afterward, then being a specialist in a desirable locale won't be an option. It'll be hospitalist or PCP for all but the most competitive applicants, and eventually the hot markets will saturate for those fields and you'll have to go elsewhere if you want a job, just like damn near every other career available in the country.
