Value-form
The Western Left academics are nowadays very happy to talk about "varieties of capitalism", but talking about "varieties of socialism" remains almost an absolute "no-no". Most Marxists continue to believe in "only one" (Marxian) socialism: either that, or nothing at all. "Either" a society or movement conforms to the true concept of socialism, "or" it does not; and if it does not, it "cannot be" socialism. However, precisely "because" there are many different Marxist beliefs about socialism, Marxists cannot agree among themselves whether Soviet-type societies were socialist, capitalist, or something else. Some countries meet with the moral expectations which Marxists have, and others do not.Originally Marx and Engels themselves had heckled the advocates of "true socialism", but later Friedrich Engels and Karl Kautsky promoted Marxist socialism as the one and true "scientific socialism" within the Socialist International. When he was 43 years old, Lenin stated: "The Marxist doctrine is omnipotent because it is true". Lenin's Communist International (a deliberate split with the social democrats) adopted Marxist socialism as its official political doctrine.
Nazism
Spengler's definition of socialism did not advocate a change to property relations. He denounced Marxism for seeking to train the proletariat to "expropriate the expropriator", the capitalist and then to let them live a life of leisure on this expropriation. He claimed that "Marxism is the capitalism of the working class" and not true socialism. According to Spengler, true socialism would be in the form of corporatism, stating that "local corporate bodies organised according to the importance of each occupation to the people as a whole; higher representation in stages up to a supreme council of the state; mandates revocable at any time; no organised parties, no professional politicians, no periodic elections".
