No book comes to mind.
The whole corporate structure of France went over to the fascists.
We need to remember just why it was that France failed so quickly.
It was because France was divided almost perfectly down the middle between socialists/communists, on the one side, and corporatist/fascists on the other.
These two domestic factions hated each other intensely, and the government was socialist, but the military command was quasi-fascist.
The degree of hatred and distrust exceeded even the current level of partisan hatred in America.
The left wing of French government was spiritually akin to the Soviets. The right wing of French government was spiritually akin to the fascists in Italy and Spain, with a dose of anti-Semitism akin to (although not anywhere near extreme as) the German Nazis.
So, when the French military collapsed, practically for the want of desire of the French general command to fight, the Parliament voted in Petain as national leader, and the French fascists took command of the government. They were nationalist adversaries of the Germans, still, but ideologically they were very much in tune with the fascist corporatists.
Now, that was virtually the whole French right.
We should remember that from 1941 until 1944 or so, practically all of the active Resistance in France was Communist. The French right was fascist, and the Nazis were their ideological allies, although the French right were still French nationalists and resented German domination. So, what you had was all of the major French industries, the entirety of it, continuing to operate, stepping up to war production, for the Germans, with French corporate leadership squeezing the hell out of French labor. The French laborer was exploited by the French corporatists for their PROFIT, and for the benefit of the whole fascist cause everywhere. Renault cooperated enthusiastically with the German war effort. THAT'S the main moral reason why Renault was nationalized as soon as the free French government was restored.
This is also why the French are specifically suspicious of corporatism.
Remember, in France during the occupation, the only fighting heroes were Communists. The French right, the republicans and business class. Were, as a class (if not always as individuals) Vichy, and cooperative with the fascists. Now, this didn't mean that they were eager to kill Jews, and there was plenty of hiding Jews. But in social terms, the French right saw in the German conquest the opportunity to bring well in hand labor and the left, kill the Communists, and establish a corporatist state in France which would focus on iron-fisted production and rule for maximum profits. Vichy was not about race war, but it WAS about class war. It was the moment of full domination by the corporate far right, and they viewed French laborers as work units, essentially livestock, to be driven to the greatest extent possible. Communists and any sort of labor organization was, of course, subversive, and murderously attacked.
THAT'S why the French are distrustful of unregulated corporatism. Because that was Vichy France. And it's why the French view labor organization and control, and direct labor presence in corporate board rooms, etc., as an essential tool of democratic control of the country. The last time the French capital class was completely unregulated by French workers, it went over as a class to fascism with a vengeance.
