What was Hitler's opinion of communism?
"The streets of our country are in turmoil. The universities are filled with students rebelling and rioting. Communists are seeking to destroy our country. Russia is threatening us with her might, and the Republic is in danger. Yes - danger from within and without. We need law and order! Without it our nation cannot survive." -Adolf Hitler
Hitler hated Communists. He thought that the goal of economics should be efficiency and not equality (he believed economic equality was WRONG) and that Communists were "rabble rousers" who interfered with patriotic production.
Communists were the very first group to qualify for sentencing to death camps, even before Jews and Gypsies. This is because Hitler thought Communism was a Jewish conspiracy to take power. He recognized that Karl Marx, the founder of Communist philosophy, had been 100% ethnically Jewish, although an Athiest, and that many Jews in Germany were Communists. Non-Jewish Communists, according to Hitler, were even worse, they were "race traitors" (Himmler quotes) who wished to share power and wealth due the Aryans with "mud-people".
It's a book showing that communism isn't an element that works in society, in my opinion. It's showing Stalin's uprising in power, and the reactions people had to it. The fact that Stalin ended up turning into the tyranical people that had ruled them previously. It's a story of history, and of political opinion. It's showing that Communism does not work.
