There is no real argument... it's a bunch of stuff they have tried to sell to pre-pods forever (diabetes, boomers, surgery, be a doc, etc etc).
It's just a cover-up for the real motive: which, as always = $$$.
The reasoning is that people want podiatry "leadership job$," they want sponsor company monies, dean job$, admin job$, faculty job$, they want resident$, fellow$, they want PP associates' pay low, boards want more member$ and exam$, etc. The glut of students and seats is just a feeder for more revenues and jobs, and it's too bad.
For the 9538th time, we don't need more DPMs than orthopedists (all specialties combined) or almost as many as gen surgeons. It's ludicrous. We should have much fewer pod schools and pods... around the number for plastics or uro or ENT or other niche specialties. But why protect the demand and income of grads? That merely helps the public and the training/income of the grads, not the "leaders."
