Mises "Socialism" enumerates many forms of socialism that in their extreme case is totalitarianism. They are all authoritarian, centrally planned, statist paradigms but come in many flavors and strategies for implementing them. Today we have multiple forms of socialism emanating from DC and Blue State Crapitals.
The Democrap version is Marxism or communism. It is "public ownership of the means of production." Think the Student Loan industry or the DOJ and HUD nationalizing the suburbs and rural America. It is "One World Government" as evidenced by the TPP and Obama taking the Iran Nuclear Deal to the U.N. It is "democratic" in appearance as it appeals to the mob by a demagogue such as Obama, Schumer and Pelosi.
The GOP Establishment favors fascist-style socialism. It is "control of the means of production." It is the Farm Bill and Export Import Bank that showers billions on favored corporations. It is owned and operated by the Crony Chamber of Commerce. The GOP Establishment loves Agenda21 with its light rail and solar boondoggles as monopolistic, fascist government breeds corruption between politicians and big business.
We also have syndicalism with our unions, especially Public Employee Unions. It is no different than the Guild system of Feudal times except that it is based on ideology instead of heredity.
