Ethiopia has long done quite well by Sub-Saharan African standards. It has a good record of human accomplishment, being the only country in the region to have developed a literary corpus before European colonialism.
But it was, until recently, extremely poor. But no longer so after a decade of some of the highest growth rates in the world, which has been faster than China’s every single year during the 2010s:
Despite Corona and the ethnic unrest, growth remained at 6.1% in 2020.
This is a vindication for the HBD theory of economic growth, which says that over the long-term, as countries exit Malthusian traps and adopt development best practices, they should converge to a level correspondent with their human capital. Ethiopian polygenic IQ probably isn’t significantly worse than Kenya’s, which has the best psychometric performance in SSA, so I expect Ethiopia to sail smoothly to its level (political shocks aside). But whether it can continue China-level growth beyond a Kenyan GDPpc of ~$5,000 is another matter.
