Ethiopians inventing a few things here and there is of no use if it’s a country where the majority lives in poverty because of corruption and violence caused by brainless tribalism.
Many formerly colonized countries achieved unprecedented levels of success.
But in Africa where corruption and tribal violence is hindering development, the foolish kleptocrats running the show always try to hoodwink their population by blaming long dead and gone colonialist powers.
