ttosca "...you still have other knock-on effects such as a lack of money being spent on consumer goods, reducing tax revenue from VAT, and a depression of businesses, which results in a loss of corporate tax."
Do the maths on my post again and you'll see that I added a pretty huge safety margin to my figures of how much tax the average individual pays. I still get to the figure of a saving of at least £12.5k and in reality it may well be (i.e. probably will be) more than that.
The lack of money being spent on consumer goods is far more problematic for the wider economy and its one of the reasons I favour tax cuts for businesses so much. Under your reasoning, private sector businesses who supply goods to public sector employees are, in effect, giving away their produce for free. Here's why; the state confiscates their wealth, the company then earns that confiscated wealth back by providing services or goods to public sector employees. It is, if you like, the flip side of the Working Tax Credit system whereby the state, acknowledging it takes too much tax from poor families, gives some of it back via a hideously complicated bureaucracy. Now, obviously, public sector employees have to consume stuff so some transfer of wealth between private and public is necessary; minimising that wealth transfer, through capping the employee head count, is essential. When Brown stuck another million or so on the governments? books (at a time of privatisation) he tipped the system towards being unsustainable.
"There are other factors to consider, such as the damaging effect long-term unemployment has on society and the unemployed"
This is absolutely correct but this is the social argument, not the economic one, which isn't the point you were making up thread.
"Another example is that personal households cannot simply print more money like the government can,"
This is the only difference between a household and a country with an independent money supply and a printing press. Even so, printing cash is not without cost and nor is it a solution to our current woes - not without causing rampant inflation.
"household borrowing costs many times more what it costs the government to borrow."
This doesn't make it a good idea for the government to borrow as much as it can for exactly the same reason as it wasn't a good idea for families to max out half a dozen interest free credit cards before the recession hit. Sooner or later circumstances change. Would you bet against this crisis dragging on for another five or even ten years? Who knows what the BoE will be paying on gilts in five years? time? I'd say it would be best to move forward hoping for the best but planning for the worst.
