The Tobin tax - also known as Robin Hood Tax - which was suggested by Nobel Laureate economist James Tobin as long ago as 1972 as a tax on all spot conversions of one currency into another, has already found support with Gordon Brown (the British Prime Minister), Angela Merkel (the German Chancellor) and Nicolas Sarkozy (the French President).
It is receiving some airtime in Australia as well and you can support it by joining the hundreds of Australians on robinhoodtax.org.au. After all, taxing those vultures is the very least we can do!
