Communist propaganda accordingly serves the same purpose as all its predecessor propaganda: to ideologically enforce the legitimacy of the working class (those who derive a living from selling their labor) as the ruling class of society. Within this context, the main counter-propaganda is "bourgeois propaganda", or propaganda that promotes the rule of the capitalist class (those who derive a living from privately owning property and capital assets). Communist propaganda is defined as a scientifically based system of the dissemination of the communist ideology with the purpose of education, training and organizing of the masses.
