Ultimately, there are not enough doctors to meet demand. Raising wages will just move them around. The supply of doctors is inelastic due to limited residency slots.
You’re ignoring the back end where hospitals have to convince insurers to pay them that much.
Keep in mind, people have to pay for these services. Pay doesn't go up in a vacuum.
Hence why all the talk about "cheap" cost of living is lacking. It's missing many quality of life components that many people value, resulting in its low nominal prices.
