Katharine sez, "Dartmouth Films are working with the Equality Trust on a documentary film of 'The Spirit Level, which aims to take the message of the book -- that more equal societies are better for everyone -- out to a wider audience. With growing unease over the last year about tax avoidance & the social effects of inequality (and the success of movements such as Occupy and Uncut), the film hopes to put pressure on governments and political parties from all ends of the political spectrum to pursue fairer policies. The film's campaign is live for three more weeks only at Indiegogo, and you can support the project by pre-buying the film or following the film on Twitter."
