In August 2015, a 32-year-old former hedge fund manager named Martin Shkreli bought the rights to a decades-old drug used to treat malaria and Aids complications and raised its price from $13.50 (£10.35) per pill to $750 per pill.
That 5,000 per cent hike briefly made Shkreli – who was later jailed for seven years for an unrelated fraud scheme – one of the most hated people in America, trashed by both Hillary Clinton and Donald Trump and branded the "Pharma Bro" in news stories read by outraged people across the world.
