Just a quick note regarding fascism in Spain. As the Nazis came into power in 1933 there was indeed already a fascist movement in Spain--the Falange. This group was both vocal and relatively well-armed. New recruits were asked when they joined if they had a "bicycle," which was code for a pistol. Members of this group took violent action against the left on multiple occasions before hostilities began in 1936.

But this group was actually pretty small. If we look at the results of the 1936 elections in Spain we can see that the influence of the Falange can easily be overstated. They got less than 0.1% of the votes in 1936, less than 7,000 votes overall. So the Falange was a vocal minority whose high rate of gun ownership and willingness to use violence gave them a much higher profile than their numbers would demand by themselves. After the war began Falange membership skyrocketed. Many joined out of a real attraction to the movement, but others joined to "prove" their loyalty to Franco's movement despite the fact that they were leftists before the war began. Given the brutal and murderous repression of the left in Nationalist Spain it is understandable that people would join their opponent out of a desire for self-preservation.

So just be careful attributing too much influence to the Falange--especially prior to 1936.

Actually, all fascist groups at the time were fairly radical. Many of the original fascist leaders were ex-socialists who came to adopt corporatism, which was fairly radical itself. Corporatism was a variant of socialist syndicalism that respected private property to some degree but also established workers rights. When Italy enacted corporatism in 1927, it's labor laws were considered the most advanced in the world.

In Germany, the Social-Democrats enacted corporatism well-before the Nazis came to power. Something else to note is that the Left-wing of the Nazi Party (the Strasserists) were actually purged when Hitler abandoned some of the more radical policies.

So there were huge differences between the traditional/conservative right and the fascist right. In Italy and Germany the right simply believed the fascists were preferable to the communists. In Spain, the right actually had a lot of contempt for the fascist Falange. They often referred to them as "reds."

I think Hitler's policies had a different rationale than the other fascists. He seemed determined to mobilize Germany for war well-before he came to power and this may explain the need to centralize the nation's industries.
