When you look into any of the leaders or voices in the fascist movement, they were all Socialists. They varied from Marxists, Leninists, or branches and factions -- but they were a pro-union, workers movements, whose rhetoric was virtually indistinguishable from other socialists unless you were deep in the weeds of how to govern to achieve socialist nirvana.
Here are some key names:
- Giovanni Gentile - The "philosopher of Fascism", who ghost-wrote Benito Mussolini's, "The Political and Social Doctrine of Fascism”, as well as many other books on the topic. He was a follower of Hegel and Marx, a member of the Fascist Grand Council in 1925, and the last president of the Royal Academy of Italy. A devout Socialist and believer that the state belonged ahead of the individual.
- Corrado Gini - The guy who wrote the book on economic fascism and invented the Gini Coefficient believed in the state above individuals, was a proponent of Eugenics (popular among the statist left). 
- Benito Mussolini - a lifelong Socialist. While he hand limited power in Italy (due to governmental structure), when he was made President in Exile, he immediately nationalized the businesses, privatized the wealth, and enacted every Socialist reform possible. The only reason he hadn't done that in Italy before then, was because of the limitations of power.
- Adolf Hitler - he never called himself or his party Fascists (though he attributed a lot to them), he was always a National Socialist, and all his plans were to enact socialism, just incrementally: first win the War with the help of private business, then Socialism.
For if the nineteenth century was a century of individualism (Classical liberalism always signifying individualism) it may be expected that this will be a century of collectivism, and hence the century of the State. —Benito Mussolini, "The Political and Social Doctrine of Fascism,” Jane Soames authorized the translation, Hogarth Press, London, 1933, p. 20. Against individualism, the Fascist conception is for the State; and it is for the individual in so far as he coincides with the State . . . . It is opposed to classical Liberalism . . . . Liberalism denied the State in the interests of the particular individual; Fascism reaffirms the State as the true reality of the individual. (p. 13) 1935 version
