The kacaan had noble goals, they wanted to transform Somalia. Although they took the authoritarian approach it could've worked if they analyzed the Somali society and figure out how to go about it. Instead they copied the models Russia had undergone it's revolution. Somalis weren't used to living under authoritarianism, they weren't workers, they weren't farmers. There was no way communism would work in such society. China took a different approach and allowed private enterprises while nationalizing national resources. Somalia was damned if they embraced Capitalism as foreign entites would exploit our resources and damned if we embraced Communism as Somalia wasn't industrialized.
The best approach would have been to allow private enterprise and nationalize major industries and national resources.
The other issue the kacaan had was they massively failed to diversify the economy, failed to explore and extract our resources and instead relied on cold war aid from the USSR. Idk if they were unable to or they simply didn't want because I haven't read enough on it but i will assume they just couldn't.
