The way we train MDs is... highly counter-productive to say the least. First a completely unrelated undergrad, which really adds no value (hint: Foreign doctors can do a fellowship and get licensed to practice in the US without having an unrelated undergrad degree pre med-school). Then med school, which is completely detached from any clinical experience. Then residency, where practical knowledge is theoretically built but in practice is more of a legally sanctioned hazing (patient outcome doesn't really matter, what matters the most is impressing whoever is slightly higher on the pecking order in order to get the spot you want).

Multiple years of zero sum games and competition against your peers. Then, once you get your license, you are supposed to make a complete 180 and start becoming a team player.

To be completely honest, if you add up the useful time spent in school, an MD is just about on the same footing as a PA/NA.
