This article is devoted to analysing the ethical commitments underlying research methodology on “brain drain” and leading participants in the public debate to deny the human right of emigration for skilled persons. Here, we identify five such commitments : to consequentialism, prioritarianism and nationalism, we add sedentarism and elitism. Based on this analysis, we argue that even though the emigration of the most talented would be a loss for the country of origin, this loss is not sufficient to require (...) that migrants themselves compensate it – either by tax payments (e.g. Bhagwati’s tax proposal) or by not exercising their right to emigrate. Moreover, to interpret public investment in education as the source of migrants’ further obligations to their country is to view education rather as a source of dividends than an access to opportunity that present generations owe to futures ones.
