I’m all for Marxism, but I haven’t observed the “body of economic theory” having any relevance, except as a snooby self-righteous justification for authoritarianism and violence.

Even if you were to strip all moral interpretation away, violence and authoritarianism is unstable and ineffective. ML’s in practice are fake progressives, because they don’t even care for finding a stable effective solution. The progression of society is no longer the point.
