Lack of residencies which are funded by the government. Medicial schools in the US try to get as many students placed into residency as possible so they control admissions to match residency slots, because if you don't have a residency you cannot become a doctor and med school costs $200k-$500k so it's life wrecking if a student doesn't match. The side effect is that we have a lot of pseudo-doctors who have roles that overlap in capabilities with doctors like Physicians Assistants and Nurse Practitioners to fill in the gap.
