I think even if some of them decide to move out of the country, it’s their personal choice but as long as they do something alongside for their country or for humanity in general it should pay off. For that part, I don’t see many desi doctors doing charity work, even the well established ones. But then that could be said about other professions too.
In this case, young doctors have broken their oath by going on strike so I have no sympathies for them.
