Althusser argues that ideology exists both by and for subjects according to Marxist theory. Ideology justifies a subject's way of life and status quo while also reproducing conditions of production. Althusser believes ideology is essential for social order by ensuring subjects unconsciously accept social norms and examples that maintain capitalism. Ideology is a necessity for subjects to fulfill their roles and desires within the existing social structure rather than seeing their unequal treatment. For Althusser, ideology is a fundamental and inseparable part of human consciousness and social formation rather than a false view imposed by the state as Marx argued.
