Question

what was a principle of marxism that american capitalists opposed?
rule by the working class
support of free - market economics
support of supply - and - demand economics
rule by business owners

Explanation:

Marxism advocates for the working class (proletariat) to take control and establish a socialist/communist society, opposing the rule of the capitalist class (business owners). American capitalists, who are part of the business - owning class, would oppose the idea of rule by the working class. Free - market economics and supply - and - demand economics are more in line with capitalist economic principles, and rule by business owners is what capitalists support, not something they would oppose as a Marxist principle.

Answer:

A. rule by the working class
