directs, and coordinates the activities of the party and the regime; corporative organization of the economy that suppresses trade union liberty, broadens the sphere of state intervention, and seeks to achieve, by principles of technocracy and solidarity, the collaboration of the "productive sectors" under control of the regime, to achieve its goals of power, yet preserving private property and class divisions; a foreign policy inspired by the myth of national power and greatness, with the goal of imperialist expansion. A. James Gregor A. James Gregor, co-founder of the International Association for the Advancement of Ethnology and Eugenics, a prominent group in the promotion of eugenics and segregation, affirmed that fascism was a "variant of Sorelian syndicalism" which also included components of neo-idealism and elitist socialism. Gregor stated that Stalinism and Fascist totalitarianism would have been impossible without the "transmogrified Marxism, that infilled both". According to Gregor: Fascism was a variant of classical Marxism, a belief system that pressed some themes argued by both Marx and Engels until they found expression in the form of "national syndicalism" that was to animate the first Fascism. Furthermore, he believed that post-Maoist China displays many fascist traits. He has denied that fascism is "right-wing extremism". Gregor's work has come under increasing criticism in the 21st century. In a review of his 2006 essay on Neofascist movements, Peter H. Merkl, of the University of California, Santa Barbara, accuses Gregor of ignoring modern work in favor of his own views, and attempting to force an out of date definition of fascism. Merkl writes: In comparing the movements of 1919 with those of the last 30 years, for example, he [Gregor] ignores the differences between the issues created by the World War I peace settlement and the struggle against non-white immigration. Roger Griffin Historian and political scientist Roger Griffin's definition of fascism focuses on the populist fascist rhetoric that argues for a "re-birth" of a conflated nation and ethnic people. According to Griffin, [F]ascism is best defined as a revolutionary form of nationalism, one that sets out to be a political, social and ethical revolution, welding the "people" into a dynamic national community under new elites infused with heroic values. The core myth that inspires this project is that only a populist, trans-class movement of purifying, cathartic national rebirth (palingenesis) can stem the tide of decadence. Griffin writes that a broad scholarly consensus developed in English-speaking social
