Honestly many ideas behind it are well meant but the whole bourgeoisie and proletariat thing isn't as black and white. Also the economic adaptation of companies and supply chains to what is needed doesn't really work properly in marxism. I like many social aspects but in a state where everyone owns everything there is no personal incentive to innovate. The economy just doesn't run as smooth and adjusted to the individual. There are many good ideas, good intentions but in the end it works better as a theory. Especially since personal needs often go unaddressed and the personal wish for wealth doesn't just disappear
