Answer:
All of the choices are correct
Step-by-step explanation:
Marx believed that depriving the masses of the basic necessities, exploiting or oppressing the poor is the major source of conflicts, whether political or social; he believed, a man's moral consciousness is not a source of his economic prosperity, but his deprivation of prosperity is the source of his moral decline.
In other words, he believes that the conditioning of a man's behaviour or morality is as a result of his historical and social existence.
From Marx's perspective, alcoholism, mental illness and prostitution are all products of the moral degeneration and estrangement fostered by the oppression and exploitation of the poor, women, and African Americans or other minorities.
