Your argument is that socialism only works in oil rich countries?

Oil is on it's way out. It's not a long term plan to build a system that depends on massive resource wealth. Especially when using that resource destroys the planet.

Cuba doesn't have oil. That apparently fits with your ideal world where countries with oil wealth are nice socialist utopias, and those that don't... well they just can't afford socialism I guess? Or maybe they get abused by a country dominated by the corporations the petro-socialist states invest their sovereign wealth into?

You do know which country Norway's sovereign wealth fund is invested in, don't you? Here's a clue: https://www.nbim.no/en/investments/all-investments/

Wait, the Soviet Union had a lot of oil wealth, why did that collapse? It seems not even petro-socialism always works.

Petro-socialism, that is certainly a creative ideology I must say.
