Sounds stifling. What’s the problem with holistic training? Except some admin does not want to pay for it?
Extreme division of labor will just create backups for some specialists and time to twiddle thumbs for others.
The opposite across society seems necessary; people need to become more self reliant across contexts. Remove industrial manufacture pipelines so more raw materials are available to the general public and make more holistic and well rounded people.
It all needs to happen in my opinion though: let the current provider models stay, but let in lots of other educational models, and empower people to take more care of themselves by giving them access to what they need. Everything is far too overregulated in medicine, or at least is regulated in the wrong way.
Even within the physician model it's broken and overregulated. Board certification is ridiculous and insane in some specialties.
I think medicine is just an amplified version of a lot of problems in the US, but it also has significant consequences for life and wellbeing.
