How is a system where if I try and make a union that demands some kind of worker control for the proletariat gets me thrown in a concentration camp left wing? Unions are basis for which the working class can defend its class interest. It you can't do that then it certainly isn't socialist. You may as well say China is socialist.
In feudalism the lord and his peasants enter a contract. The Lord basically own the peasants and the land they work. The Lord looks after the peasants but he owns the peasants. Fascism is basically that but in an industrial setting. It has nothing to do with socialism. Socialism is everything to do with worker self autonomy in the economy. Fascists regimes put workers trying to exercise self autonomy up against the wall for a firing squad.
I'm not a serf and I'm not going to desecrate all the (mass) graves of working class people who thought against fascism by pretending fascist economics is somehow socialist.
I think you are confusion any sense of collectivisation with left wing. I'd rather neoliberal economics than fascist economics.
"Both the Left and the Right have advocated forms of collectivism. The word fascism derives from its symbolic use of the fasces of Ancient Rome, with rods bound together to signify collective strength. Fascism subjected individualism to the collective whole. Similarly, nationalism extols the nation over the individual. If you insist that collectivism is Left, be warned that fascism and nationalism also incline in the same collectivist direction."
