another socialist paradise
Natural resources in a country with good institutions benefit the economy. Natural resources in a badly-run, corrupt country actually make things worse. We're seeing exactly that in Venezuela, Nigeria, Angola, etc. The system of government in corrupt countries like this doesn't really make much difference, because they're typically just lip service to whatever political ideology they choose anyway.
Yeah, I've no evidence to suggest it, but I'm sure the socialists are screwing up Nigeria as well and the Democratic Republic allof the Congo and well everywhere really.
The biggest reason under developed countries stay that way is corruption. There can be no prosperity with endemic corruption and you find it in poor countries that purport to be right wing, left wing and all points in between.
Many of these governments pretending to be socialist aren't remotely so, just populist cult of personality regimes of right and left based on corruption and division.
