The Robin Hood Tax - Resurrecting and Rebranding the Tobin Tax
Leveraging the total and well justified outrage at the banks over their massive bailouts, The Robin Hood Tax project rebrands the Tobin Tax idea (and prior to that Keynes' idea of a tax on all financial transactions) to try to divert bailout money and questionably speculative activity (rather than wealth creation) to assist in social causes, combatting climate change and other social priorities.
Totally love this idea, even as a former economist. I'd love to see it pushed despite practical difficulties. Oh, and absolutely fantastic performance by Bill Nighy in the Curtis directed short (and how can you not love seeing the Gherkin in the background?).
