"to the extent that we keep having to pillage the third world for theirs"
Um....bluntly: NO
I've lived in those third world countries at various times in the past.
People do the medical courses _specifically_ to get jobs elsewhere (because that's where the money is). If the promise of overseas employment wasn't dangled as a carrot (it figures highly in all the adverts) they wouldn't be doing the courses in the first place.
There's no pillaging involved. The moment the UK and others started restricting intakes, the medical schools concerned saw a significant fall in their enrolments.
The countries in question export _people_. They regard "remittances" back to home as part of the national economy and overseas workers are regarded as semi-heroes even if they're working illegally and find themselves deported.
Of course the flipside of people going into these professions for the money is easy to see - it's no coincidence that these nationalities figure highly in patient abuse stats. They're not there for the care aspect of things and they come from cultures where casual violence and elder abuse is the norm (this is an observation from living in such places).
