The covid-19 pandemic has shown us and proved to us that you cannot have an isolated system.
What affects one country health wise and otherwise should be of interest to other countries. And asuch I am suggesting that the training of teachers and nedical doctors world wide should be a collective responsibility
.irrespective of the country of origin any one who wants to train as a Doctor or Teacher an certified suitable should be provided with free education and on qualifying, renumeration would very made by a world body not by the country of origin.for instance money looted from Africa some of it can be used for this purpose the western piwer know where the looted funds are
Remuneration would be made relative to the economic state of the country of origin
