Sarah Butler asks, can the Bangladesh garment industry become ethical and profitable?
The collapse of the Rana Plaza clothing factory in Bangladesh was the deadliest disaster in the history of the garment industry. It brought about a series of recriminations, alliances, promises and calls for change.
With Bangladesh's clothing industry, predicted to quadruple in size over the next twenty years, a New York based private equity firm has come up with an idea to make Bangladesh's factories sustainable and efficient - as well as profitable. With backing from the Soros family, Tau Investment Management's plan is a bold one. They aim to provide a capitalist solutions to capitalism's failures.
The Guardian's Sarah Butler travels to Dhaka to meet Tau's owners and asks whether the Bangladesh factory owners need their help.
