I guess when we talk about immigration, we should look at the other side of the story too.

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

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.
