I want to be careful about this argument, because it can too easily slide into a simple populism that does more harm than good. Not everyone who went to a private school is incapable of empathy. Not every politician with a comfortable background is unfit to govern.
But there is a version of this argument that stands even under the most rigorous scrutiny, and it is this: the social composition of Britain's governing class has a measurable effect on the policies it produces.
The Evidence
Studies of parliamentary voting patterns, policy outcomes, and regulatory decisions consistently find that decision-makers design systems that reflect their own experiences and assumptions. This is not malice — it is human nature.
When universal credit was designed by people who had never needed to claim it, the waiting time, the digital requirements, and the inadequacy of the emergency provision reflected not hostility but ignorance.
The Talent Question
A political class drawn from a narrow social pool is also a less talented political class. Half of the available talent — the half that attended state schools, didn't go to Oxbridge, worked in ordinary jobs — is systematically underrepresented.
The connection between social diversity and policy quality is not just about fairness. It is about competence.
