Hitler had a very broad opinion on democracy. If one gets a chance to read his biography, he gets to know why this man acted like the way he did. Some of the comments he made about democracy are :
Hitler found no appeal in Western democracy partially because of its slow pace. According to his logic "One works best when alone." This adage, commonly attributed to Hitler, perfectly sums up his views of democracy and parliamentary-style government. He believed that individuals operating in a democracy are not brought to their fullest potential due to the ultimatums and compromises (both in principle and practice) that commonly occur: ...democracy will in practice lead to the destruction of a people's true values. And this also serves to explain how it is that people with a great past from the time when they surrender themselves to the unlimited, democratic rule of the masses slowly lose their former position; for the outstanding achievements of individuals...are now rendered practically ineffective through the oppression of mere numbers. (Rauschning 785)
he believed "fostered class conflicts at the expense of national unity"
Hitler despised the parliamentary establishments of democracies. In his 25-Point program, he criticized the corrupt nature of representatives: "We oppose the corrupting parliamentary custom of filling posts merely in accordance with party considerations, and without reference to character or abilities" (Hitler Historical Museum 11)[3].
