If you stick to spend as a proportion of GDP that's somewhat irrelevant. If the economy grows at a slightly slower rate then the spend as a proportion grows slightly slower also.
As I said increasing spending by 3-5% per year in line with GDP growth would have been sensible. Increasing spending at twice the rate that the economy was growing is stupidity.
I don't understand the obsession with accruing mountains of debt just to artificially inflate the economy in the short term. The chickens always come home to roost so the artificial wealth creation in the early 00's is now being paid for by the current generation.
Also in terms of it "taking money out of the economy", that's not really the case given that we'd still have debt. It's merely rebalancing a historic imbalance. We also have a huge pension black hole along with a massive public debt that we're dumping on the next generation so a bit of common sense is easily justifiable.
Do you know what is really "taking money out of the economy" though? The several hundred billion in interest that we've paid since 2001.
Out of curiousity though if you believe in a large budget deficit when the economy is regarded as at the peak of a boom, what do you think the deficit should look like in a recession and how/when would you go about balancing the books?
