Uh, no we haven't established your premises as being factual.
Moreover, African countries by and large had 20 years before the "Washington Consensus" or neoliberalism took over in which many countries tried an unforuntate mixture of ISI/socialism and poorly run SOEs.
ALSO, it was ISI policies which pushed countries like Tanzania over the edge and forced them to take bitter medicine from the IMF/World Bank in the form of neoliberal restructuring.
It's fairly insulting to say I've fallen for "propaganda". Rather, you've fallen for pro-ISI propaganda despite evidence pointing to ISI failures on the African continent. There's no excuse for proposing the same failures which have set Africa back.
Read the paper I posted earlier before you spout nonsense about "propaganda".
Arguing about elites isn't "semantics". African elites all over the continent have doomed their countries by basing their economic programs on short-term political gains. That's why in many countries, elites benefit the most from land/corporate grabs. Whether it be in Mugabe's Zimbabwe or Mobutu's Zaire.
