So why would 4 be E and not A. Wouldn’t a country with a high dependency ratio need to have a well funded education system to support the young that are dependent and healthcare for the old people?

QUESTION: I thought “brain drain” was defined as the “large-scale emigration by talented people”? That’s how it’s defined in my APHG book 🤔

Maybe I just haven’t made the connection between why the talented people are moving to another country?? IDK but if you could explain that please it would be so helpful
