I suspect this is based on Marx's analysis of the creation of value. That is, for Marx only primary production creates value, all other economic or human activity destroys value. So for example in Marxism making a clock creates value, but transporting that clock from the factory to a shop, giving it shelf space, advertising it and selling it to a customer all destroy value. They are additional services that increase the cost of the product, and Marx actually used the term parasitic for these activities and argued they should all be minimised or preferably eliminated.
This resulted in Marxists creating uniform, identikit societies with standardised products directly distributed wherever possible. No advertising, no consumer choice because the process of accumulating the information necessary, and selecting products on an individual basis instead of collectively is wasteful.
The result was actual productivity in the real economy collapsed because it turns out some of these parasitic activities are kind of important. They ruthlessly stripped out all the bullshit and produced stale, drab societies of bored hungry drones. Thanks guys.
Who actually needs plays, books of fiction, music, nice clothes, holidays to pretty places? Who needs nice haircuts, polished nails, stylish cars, waited service? All of that is bullshit we don't need.
The only slight problem is it eliminates everything that actually makes life worth living. It eliminates all forms of aesthetic and cultural value, recognising only productive economic value, devoted to the activity of production itself. It suborns human value to material value.
