The former United Nations secretary general Ban Ki-moon has denounced the United States’ healthcare system as politically and morally wrong, and urged American leaders to enact publicly financed healthcare as a “human right”. Ban made the comments in an exclusive interview with the Guardian in New York, as part of his work with The Elders, a group founded by Nelson Mandela to work on issues of global importance, including universal health coverage. The US has the world’s most expensive health system, accounting for nearly one-fifth of American gross domestic product and costing more than $10,348 per American. The United Kingdom, by comparison, spends a little under 10% of GDP according to the latest available statistics, and healthcare is free at the point of delivery.
