Its a question without an answer. State capitalism isnt really a thing. Or i should say all capitalism is state capitalism? Capitalism is literally backed by capitalist states and neoliberalism as an ideology is based around using the state to increase profits for companies lol. If anything is state capitalism its neoliberalism.
I'm no expert on Libya but I'd say he was probably a social democrat anti-colonialist. As far as i know he pursued your typical social democrat reforms and programs while nationalizing natural resources that had previously been held by colonial powers? Altho pls correct me if my memory is wrong on that. I wouldnt say he was nationalizing out of some desire for collective ownership just out of a desire to get it away from imperialists.
State Capitalism as a term is just used as another bs way for western "leftists" to criticize every AES state they can. If Socialism succeeds suddenly its state capitalism.
