Yes! It's a useful lens – just as Hayek is. No-one has a monopoly on absolute truth in the social sciences, so understanding (and empathizing with) all the framing narratives, most all of which have some kind of a point, is crucial to being able to navigate these kinds of discussion.)

Understanding Marxist (and Hayekian) thought has been very helpful to me in framing my own politics – which, ironically enough, wind up being moderate market/social liberalism in the European tradition.
