"There is no magic money tree," as Theresa May put it during the snap election of 2017 - virtually the only memorable line from one of the most lackluster campaigns in British history. The phrase has been repeated endlessly in the media, whenever someone asks why the UK is the only country in Western Europe that charges university tuition, or whether it is really necessary to have quite so many people sleeping on the streets.The truly extraordinary thing about May's phrase is that it isn't true. There are plenty of magic money trees in Britain, as there are in any developed economy. They are called "banks." Since modern money is simply credit, banks can and do create money literally out of nothing, simply by making loans. Almost all of the money circulating in Britain at the moment is bank-created in this way. Not only is the public largely unaware of this, but a recent survey by the British research group Positive Money discovered that an astounding 85 percent of members of Parliament had no idea where money really came from (most appeared to be under the impression that it was produced by the Royal Mint).
