One of the main properties of many of the communist revolutions of the 20th centuries was the mass killing or removal of property of the landed gentry in those countries - sometimes more directly violent than others. Cambodia, China, Vietnam, N Korea, etc.

I think recent history has shown that simply killing the Bourgeoisie tends to just eventually create another in the form of whoever had the power to do the other killings, and not always to better ends for the people. That form of communism has been shown to not really work. Democratic socialism though seems to work out pretty well for people.
