Being a wealthier nation does help to develop the public heath initiatives and infrastructure, though the reasons for the poverty in sub-Saharan Africa are in no small part tied to the many centuries of exploitation by wealthier colonial nations. Much of post-colonial Africa started on the path of independence 50-60 years ago after centuries of resources being exploited and populations subjugated, and some areas were still under colonial rule in the 70s. The IMF and other post-colonial organizations have managed to institutionalize western imperialist-style economic exploitation without needing to bother with military occupation. It will take a very long time for those countries to recover from centuries of abuse (much ongoing) and begin to develop a stable national infrastructure that could support the kind of economic growth and the ability to manage natural resources responsibly.
