The US Koch brothers provide substantial funds to the George Mason University to ensure it remains a bastion of so-called libertarian, free-market thinking. The brothers don’t really want a free market but it just serves their political and commercial aims to tell everyone that is what it is all about. The Economics Department at this university pumps out propaganda about the virtues of deregulation. One academic (Bryan Caplan) goes further and claims that democracy is a bad idea when compared to taking the advice of economists who advocate free markets. This idea that somehow policy choices conditioned by what would advance the best interests of the public are inferior to those advocated by economists who know what is best for all of us has permeated the debate over the last few decades and led to some very undesirable developments. This was on my mind when I was reading the Manifesto of the British Labour Party which proposes, wait for it – a “Budget Responsibility Lock” – as a framework for fulfilling its responsibilities to the British public. This is a ridiculous proposal.
