Professor Tim Evans discusses the way in which an ageing population and fewer young people is creating huge problems for our economy. Money is not necessarily the answer. We are running up the down escalator and public services must be reformed. He considers an article which points out how even our top institutions and economists don't understand money and how it is lent into existence from thin air. Lastly, he recaps an article from an American think tank which points out how 1990s libertarians almost inadvertently started developing early forms of digital cash before the arrival of the internet.
