 This is because of the lack of employment for secondary school graduates (which she suggests is true to many countries in Sub-Saharan Africa), she suggests that another reason why this might be true is the lack of quality secondary education (such that increased time spent in school has no benefits).Furthermore, she argues that this might be true because many secondary school graduates are employed in jobs that are low in productivity, thus reducing the potential for economic growth.Finally, she argues that there is a lack of physical capital and other “complementary inputs” in Sub-Saharan Africa that would otherwise encourage productive labour in the region.
