According to Karl Marx, laborers really produced all wealth, and the business owners (capitalists) were the recipients of the wealth in the form of profits.

This is true.

Explanation:

Marxist theory follows David Ricardo´s labor theory, stating that human labor is the source of value. The capitalist does not pay workers for the full added value of the good produces, he only pays them a salary for subsistence. What remains is surplus labor and it creates surplus value. The capitalist takes his profit from this surplus value. Thus he exploits workers.

the ss was the main organization responsible for the genocidal murder of around six million people of european ethnic minorities, essentially jews, in the holocaust. the members of all its branches committed war crimes and crimes against humanity during the second world war (1939-1945). likewise, the ss were involved in commercial enterprises and exploited the inmates of the concentration camps as slave laborers.

the tortures and assassinations committed by the ss were the result of an ideology developed long before the armed conflict, this ideology was based on the racial supremacy of the germans over the rest.
