The most important difference between Marxism-Leninism and reformism is the problem of classes and class struggle. Lenin wrote "The question of the class struggle is the basic question of Marxism." Reformists criticize the Marxist theory of class struggle and dictatorship of the proletariat in order to preserve the domination of the bourgeoisie. They deny the existence of classes in the bourgeois state. Fritz Klenner, for example, in Austria informed the workers that they are facing a public employer and not capitalists. Why? Because 26.2% of employees work in a "public sector" and the public capital investments make up half of the total capital investments!
