OTTO BAUER
There were many British and American capitalists, like Lindbergh, who were great admirers of Hitler and Mussolini and supported the Fascists.
At the time, this was not popular with many socialists who had given up on the lack of fairness and equity of the capitalistic system. A century later, most politicians and political philosophers had given up on socialism ever meeting Bauer’s test, and Capitalism was well ensconced in Western Democracies.
He was wrong because he—and many others in the world-- never considered the possibility that the Russian Communists would be so brutal and kill so many people who resisted the Communist takeover of these economic sectors.
Otto Bauer was an Austrian Social Democrat who is considered one of the leading thinkers of the left-socialist Austro-Marxist grouping. He was also an early inspiration for both the New Left movement and Eurocommunism in their attempt to find a "Third way" to democratic socialism.
