In the early 2010s, there was a lot of pushback from up-and-coming left media figures like Owen Jones and Laurie Penny to criticisms of their PMC and educational backgrounds.

"So what if we went to Oxford, or if our parents were solicitors?", the line of defence went. "Our hearts are in the right place. We fight for the many, not the few."

Ten years on, seeing where PMC domination of the left has taken the movement, we can revisit those criticisms and see the importance of the original pushback.

What a PMC parental background and a prep-school and Oxbridge education tend to provide their beneficiaries with is a high degree of entitlement, verbal polish and presentation, and an often unshakeable personal confidence.

Combined with the utopian and improvement- and uplift-focused aspects of left thought, this prior socialisation tends to produce a highly authoritarian form of left-managerialism, one in which the PMC left appoint themselves both moral spokespeople and moral technicians.
