Trump is a spot on clear Fascist. If experts are not enough (some who left already) then just read any books before recent times and cope with the fact nobody time traveled to write biased books on Fascism to smear Trump in the future.
Generic socialism, is the needs of the many out weigh the needs of the few. It's the rationale behind almost everything; The NAZI used it and their greatest enemy, the Communists also used it (and "Socialists" as a political group are different and are also not Communists. ) Adam Smith the father of Capitalism (a Marx invention) he argued socialism was best served by capitalistic competition (and strongly apposed crony rent-seeking capitalism; which is anti-competitive.)
Bernie is far more like the greatest president, FDR who is a populist socialist. China ignored the idiotic advice/propaganda of the US Chicago school of economics etc. which ruined everything, everywhere. China took the best of FDR and world history and made more progress than anybody in the history of the world. Their authoritarian system facilitated rapid change; as that is it greatest advantage, but as Franklin said, any form of government is fine if it is well administered. The implication being, the real problem is achieving and maintaining good administration. Also good luck is greatly under considered, especially with our "hero worship" of successful people.
