Adorno is also accused of a lack of consistency in his claims to be implementing Marxism. Whereas he accepted the classical Marxist analysis of society showing how one class exercises domination over another, he deviated from Marx in his failure to use dialectic as a method to propose ways to change. Marx's theory depended on the willingness of the working class to overthrow the ruling class, but Adorno and Horkheimer postulated that the culture industry has undermined the revolutionary movement. Adorno's idea that the mass of the people are only objects of the culture industry is linked to his feeling that the time when the working class could be the tool of overthrowing capitalism is over. Other critics note that "High culture" too is not exempt from a role in the justification of capitalism. The establishment and reinforcement of elitism is seen by these critics as a key element in the role of such genres as opera and ballet .
