My Answer: Sort of. Not Really. But Definitely Sort Of.
As a technical textbook definition, Marx’s definition of socialism is still the most widely known and accepted. Socialism is public ownership of the means of production. The Fascists left property in the hands of it’s owners, so…by definition, NOT socialists.
But wait…after that it gets a little more grey. Because Mussolini (the real inventor of fascism) WAS a committed socialist before WW1 and adopted the idea of a centrally planned economy. But he recognized that the way to get political support was to scare the entrenched aristocracy LESS than the socialists did. So his way to a centrally planned economy was to let the rich continue to own the means of production, but use formal and informal means to direct their activity.
This sometimes meant above board means of Trusts and Industry Boards and the like that directed companies and industries what to make, what to charge, etc. Sometimes it was less formal. When a Nazi representative shows up at your factory and tells you that the party would prefer you making helmets instead of soup bowls, you don’t REALLY have the option to say ‘no’. Everyone knew those trains headed east weren’t taking people to some nice peaceful life in the east. They may not have known the DETAILS, but they got the gist.
So while the Nazi govt didn’t OWN the means of production, it did CONTROL it. So I think the argument could be made, that if this isn’t socialism, it’s certainly RELATED to socialism. A cousin perhaps. Or perhaps the Marxist definition is too narrow. Perhaps it should focus on central planning and govt CONTROL of the economy, rather than OWNERSHIP.
Now, it’s ALSO worth saying that even if we accept that fascism were some kind of cousin to socialism, it’s still not the same. Socialism is a purely ECONOMIC idea. We can debate whether it has political implications towards autoritarianism (I think it does), but it certainly doesn’t explicitly advocate for it. Fascism DOES.
Fascism is a political AND economic policy mix. It advocates a totalitarian govt explicitly. It advocates a nationalistic fervor explicitly. It’s not purely an economic model. So it’s not even trying to be the same thing as socialism. It may be borrowing some ideas, but it’s NOT the same.
Also, I should point out that Hitler himself was asked this question. And while I don’t have the exact text of his response, he said ‘yes’, that fascism IS a kind of socialism. He said something along the lines of ‘what difference does it make who holds the deed to the factory if I am telling them what to make, who to sell to, and what price to charge?’ Again…that’s me paraphrasing from memory…I read the quote a decade-plus ago.
While I certainly don’t consider Hitler a reliable source on… well, anything…. it is interesting to see that he himself viewed his movement as socialist in some degree. Even as his group persecuted socialists because they were a political rival.
