My serious point is that there's no way tax cuts could produce *enough* disposable income to allow us to start spending our way out of recession. The current crisis is an inevitable product of a capitalist economic system which shuns government intervention and fiscal accountability, and promotes consumer spending to create untenable levels of credit. The answer is government intervention (I would go as far as nationalisation), direct accountability, and a drawing away from unsustainable levels of credit (like a mutual loan company, you lend what you have). The 'stimulus cheques' sent out in the States did nothing, as far as I'm aware, to help the economy, and certainly didn't head off the current situation, which -- as Haven says -- was not a result of a lack of consumer confidence, but a trigger for it.
I do agree that Labour tax policy has moved uncomfortably towards a Conservative position: historically the Tories have been very successful in presenting themselves as the party of lower taxes while demanding less from the rich and more from the middle classes than Labour. However, two elections ago, the difference between the tax income projected by the two parties was less than 1%. That's not the kind of money that's going to make a difference or that can cover spending cuts.
Slashing public spending might feel temporarily as though we were being appropriately hair-shirty about the whole thing, but it would be much more likely to lead to a further decline in economic stability, partly because the correlations presented between spending cuts and tax relief usually don't add up, partly because some service providers would have to start finding the money in other ways, and partly because some people would lose their jobs. It's all very well for you to say that we have too many civil servants anyway, but a) I don't think that means we should feel any less concerned for the people employed by the civil service, and b) the people who lose their jobs would, in the majority of cases, not be civil servants, they would be refuse collectors, the people who clean the town hall, lollipop ladies etc, etc: people already undervalued for doing essential jobs.
