Name one fascist who nationalized anything? You can't because none of them ever did, they created capitalism and private property just as sacrosanct as before. Hitler for example only ever nationalized the property of Jews, as Mussolini did. Mussolini in his late days of the RSI made overtures to his Communist partisan opponents that he wanted to nationalize property, he never did and they never brought it- which is why it was Communists who shot Mussolini.

Fascism is extreme measures, yes, but it's only extreme measures to preserve capitalism when it is in such danger from worker's liberation movements, as it was during the Great Depression etc.
