The world is undergoing a populist revival. From the revolt against austerity led by the Syriza Party in Greece and the Podemos Party in Spain, to Jeremy Corbyn's surprise victory as Labour leader in the UK, to Donald Trump's ascendancy in the Republican polls, to Bernie Sanders' surprisingly strong challenge to Hillary Clinton - contenders with their fingers on the popular pulse are surging ahead of their establishment rivals. What Sanders is proposing ... is a real financial revolution, a fundamental change in the system itself. Banks today have usurped the power to create the national money supply. As the Bank of England recently acknowledged, banks create money whenever they make loans. Banks determine who gets the money and on what terms. How can banking be made to serve the needs of the people and the economy, while preserving the more functional aspects of today's highly sophisticated global banking system? We could have a system of publicly-owned banks that were locally controlled, operating independently to serve the needs of their own communities. Making these banks public institutions would differ from the current system only in that the banks would have a mandate to serve the public interest, and the profits would be returned to the local government for public use.
