In fact, an average M.B.B.S is more likely to make money in a remote rural area than in an urban setting.

I really doubt it, despite higher prevalence of diseases and lower competition. The difference in paying capacity itself ought to be enough, but the rural folk are also less likely to approach a doctor in the first place.

Like for many other things, building good roads will probably go a long way in improving rural health. My native village doesn’t have a doctor, and the village is not asking for one. There are two medium-sized towns within 30 km range, and the roads are good (both are toll roads) so it is usually a matter of 30 mins max to reach a reasonably qualified doctor.

You would notice that in case of heavy traffic, it can take just as much time to reach a doctor in Delhi.

Occasionally, health camps are organized by the district administration to take care of education and awareness issues.
