Why were the communist ideas of Marx appealing?

For some people the idea of the means of production being owned & operated the central government by for the sole benefit of the people & its workers was appealing. The large industrialists large landowners & their unfair profits would be eliminated.

All money in excess from Government operated factories & farms could be used to raise wages, improve social benefits or be plowed back into improving industries.

Private property being abolished would place everyone at the same level in that category.

The idea that at some point in time, "government" would be unnecessary and withered away appealed to some intellectuals.

Democratic socialists were not happy however, as Marx called for a violent overthrow of governments in order to install the Dictatorship of the Proletariat. This meant bloodshed and perhaps civil war. They were also unhappy at the prospect of an authoritarian dictatorship and the end of voting.
