In Mein Kampf: Volume Two - The National Socialist Movement: Chapter V: Philosophy and Organization, Hitler wrote:
In short, tear down the existing social order and replace it with the totalitarian state.Any new philosophy of life will bring its ideas to victory only if the most courageous and active elements of its epoch and its people are enrolled under its standards and grouped firmly together in a powerful fighting organization. To achieve this purpose it is absolutely necessary to select from the general system of doctrine a certain number of ideas which will appeal to such individuals and which, once they are expressed in a precise and clear-cut form, will serve as articles of faith for a new association of men. While the programme of the ordinary political party is nothing but the recipe for cooking up favourable results out of the next general elections, the programme of a philosophy represents a declaration of war against an existing order of things, against present conditions, in short, against the established view of life in general.
This reminds me of Rousseau. Edmund Burke, cited in Burke’s Defense of Natural Rights and the Limits of Political Power, "excoriated the radical French revolutionary Jacobins (along with their English followers) who would soon launch a campaign of mass murder carried out in the name of The Rights of Man. Burke recognized the grounding of such hypocritical violence in the abstract theorizing of the Jacobins’ patron saint, Jean-Jacques Rousseau, whose fantasy of an idyllic state of nature placed the blame for all human miseries on the imperfections of social and political institutions impinging on absolute rights—rights that could be made real only by an overawing, total state."
In short, tear down the existing social order and replace it with the totalitarian state.
Both Hitler and Rousseau represent the left and its agenda.
