According to Marx,the distinguishing factor in determining what class people are in is:

A) the amount of income and wealth they possess
B) the community in which they reside
C) their level of influence in society
D) their prestige
E) the source of their income

According to Marx, the source of a person's income is the distinguishing factor in determining their class. He believed that those who owned and controlled the means of production (the bourgeoisie) held power and oppressed the working class (the proletariat) who sold their labor for a wage. Therefore, it is the ownership of property that determines one's class.
