Not every problem someone has with his girlfriend is necessarily due to the capitalist mode of production.Professor Marcuse was not always wrong. Jewish, he left Germany in 1933, coming to the US 1934 and becoming a US citizen in 1940. He ended up teaching at the University of California, San Diego. I would say those are the moves of a pretty smart person. It was just that he may have been wrong about the free market.
