Michael Winterbottom and Russell Brand have made a film about inequality. They were very struck when Oxfam came up with the figure that 80 of the richest people have as much money as half of then entire population. Michael went to Mukuru (Nairobi) to show grotesque this figure is. He did that by asking 80 local activists to become the 80 billionaires for the day. They all got on 2 buses that travelled through Mukuru.
