Communism and Marxism won't ever work because it is based on an adolescent fantasy(1) of Marx's, where two great forces collide, destroying the present order and a new order coming out of the chaos. All the rest of his work had the objective of proving forth his fantasy. By sifting the record of history and UK bureaucracy, throwing out everything that did not align and keeping that which did. Marx natters on interminably about industry and the working class, without ever having set foot in a factory his own self and holding factory workers in contempt.
To take Marx seriously is to beclown oneself.
(1) As in, "fantasy Marx had while a teenager."
