Probably because those with loads of money can easily go elsewhere, while the "little people" are stuck here.
Let's face it, the banks may have acted as the detonator, but in this country we've been wasting billions for years, so this whole mess was inevitable (although maybe not on the same scale). Taxes would have had to have gone up sometime and by some degree - which one doesn't hurt?
This is worrying though - from Labour's chancellor:
"Earlier, Mr Johnson had been dismissed as ‘simply not up to the job’ by the Tories after a string of blunders over Labour’s economic policy.
As well as talking of a National Insurance rise, he was confused over when Labour would aim to eliminate the structural budget deficit, initially telling the BBC it would be 2015-16 before later saying he ‘probably’ meant 2016-17.
He was unclear over when Labour’s own cuts would start, saying that 2011 ‘has to be about jobs and growth’ rather than cuts, when in fact Labour’s own plans are for the biggest cuts to happen in 2011.
And he suggested he had not even read Labour’s last Budget, on which its economic plans are based, telling a BBC interviewer: ‘You’ve probably read more of it than I have.’
