I am not anti immigration, but in this cpntext migration out of Ghana is causing real problems for the people there.

Ghana patients in danger as nurses head for NHS in UK - medics

Same report cites social media as being partly responsible for this brain drain.
If anything, richer countries should surely be producing enough nurses & medical professionals to be able to send them overseas to gain more varied experiences and share this expertise world wide.
A good reason to tax the billionaires, corporations and find a way of helping countries such as Ghana keep hold of their essential workers, for the BENEFIT of the people in Ghana.
