Much of Africa is indeed the land of opportunity (with the exception of South Africa, which has serious structural and political issues, and is in a sort of terminal malaise).

The calculus changes once children enter the picture though. The continent (a huge place to generalise about) isn't exactly the sort of place to risk raising a family, unless you are rich enough to be able to maintain a ready escape plan for them, and to educate them privately. You don't want to risk having them complaining in 20 years about the same things the OP talks about and being stuck here.
