The Nazis and Mussolini's fascists were always an employer-alligned right wing movement. The supposedly left wing part of the movement was a pose. Henry Ford knew this when he financed them starting in 1921. German Harvard grad Putzi Hanfstaengl engineered the bourgeois-ification of Hitler's rough edges and entry into Munich's elite and the German business elite's financing of the Nazis, knowing full well that the S in the NSDAP was just for show for working class Freikorps veterans addicted to the repressed homosexuality male-bonding of street fighting.
"“Adolf Hitler wrote, “only a single great man, Ford, [who], to [the Jews’] fury, still maintains full independence … [from] the controlling masters of the producers in a nation of one hundred and twenty millions.” Speaking in 1931 to a Detroit News reporter, Hitler said “I regard Henry Ford as my inspiration,” explaining his reason for keeping a life-size portrait of Ford behind his desk.[84][79] Steven Watts wrote that Hitler “revered” Ford, proclaiming that “I shall do my best to put his theories into practice in Germany”, and modeling the Volkswagen Beetle, the people’s car, on the Model T….Ford also paid to print and distribute 500,000 copies of the antisemitic fabricated text The Protocols of the Elders of Zion. Historians say Hitler distributed Ford’s books and articles throughout Germany, stoking the hatred that helped fuel the Holocaust.”

The Nazis were always right wing, adroitly using Jew hatred, what German socialists August Bebel and Ferdinand Kronawetter called "the socialism of fools" (Der Sozializmus der Dummen Kerle), to pry German enough workers away from the Socialists and Communists. If Stalin had had the good sense to deploy in Germany the popular front policy used in France in 1936 instead of having the KPD call the SPD "social fascists", the Nazis might never have come to power.
The Bolsheviks' gangster and centralized approach to organizing the seizure of power inspired many imitators on the right. So did America's Jim Crow legal codification of racial hierarchy: https://www.theatlantic.com/magazine/archive/2017/11/what-america-taught-the-nazis/540630/
That's why in 1934 the Nazis sent a team of lawyers to meet with the American Bar Association to study Jim Crow segregation laws before they drafted the Nuremberg Laws in 1935.
The Nazis' plagiarism of its leftist original shows how conservatism is purely reactive, which is why we call conservatives "reactionaries". Their innate hostility to novelty makes them utterly incapable of originality beyond such plagiarism.
