A good article at The Federalist about the similarities between the Nazis and the Communists:
It wasn’t only theoretical. Hitler repeatedly praised Marx privately, stating he had “learned a great deal from Marxism.” The trouble with the Weimar Republic, he said, was that its politicians “had never even read Marx.” He also stated his differences with communists were that they were intellectual types passing out pamphlets, whereas “I have put into practice what these peddlers and pen pushers have timidly begun.”
It wasn’t just privately that Hitler’s fealty for Marx surfaced. In “Mein Kampf,” he states that without his racial insights National Socialism “would really do nothing more than compete with Marxism on its own ground.” Nor did Hitler eschew this sentiment once reaching power. As late as 1941, with the war in bloom, he stated “basically National Socialism and Marxism are the same” in a speech published by the Royal Institute of International Affairs.
Nazi propaganda minister and resident intellectual Joseph Goebbels wrote in his diary that the Nazis would install “real socialism” after Russia’s defeat in the East. And Hitler favorite Albert Speer, the Nazi armaments minister whose memoir became an international bestseller, wrote that Hitler viewed Joseph Stalin as a kindred spirit, ensuring his prisoner of war son received good treatment, and even talked of keeping Stalin in power in a puppet government after Germany’s eventual triumph. His views on Great Britain’s Winston Churchill and the United States’s Franklin Delano Roosevelt were decidedly less kind.
Go here to read the rest. Hitler never had the time to bring his full plans to fruition. In the Bunker he lamented that he had been insufficiently radical and he should have liquidated all German conservatives. When it came to economics, Hitler’s ultimate goal never changed:
We are Socialists, we are enemies of today’s capitalistic economic system for the exploitation of the economically weak, with its unfair salaries, with its unseemly evaluation of a human being according to wealth and property instead of responsibility and performance, and we are all determined to destroy this system under all conditions. In the future there must be no ranks or classes, and you must not let them begin to grow in you!
