Which was not an idea expressed by karl marx in das kapital or the communist manifesto? a) capitalism should be overthrown. b) labor unions will make life better for workers. c) there has been a struggle between classes throughout history. d) when workers revolt, personal property will no longer exist

The correct answer is B) Labor unions will make life better for workers.

Labor unions would not do well for a fully communist country because they would oppose the state, and as the state is the ultimate representation of people in a communist country, then they would be going against the people themselves since it is understood that a single communist party would already make life good for workers without having unions interfere.
