From looking at the survey of the tax system (08-09) : http://www.ifs.org.uk/bns/bn09.pdf
It seems the amount they 'got' was £545.5BN, so £545,500,000,000... Nice
And they're spending £800,000,000 on this 'aid' - 0.14% of their total income... On a hypothesis, a prediction of the future, even 'fortune telling'?
Of course 0.14% doesn't sound like much, but how many OAP's could that warm/keep alive this winter, prisons be built to protect the public, be put into public transport (Oh, that'd help the penguins), lower council tax, go into the NHS (With efficient management), or anything to make the people who are paying it happier to be paying it?, OR : Build nuclear power stations so they don't have to burn the fossil fuels they claim are going to be the end of us as we know it?...
Meh.
