" Well, yeah that is perfectly true - stimulus packages are only meant to help temporarily; until the private sector is capable of picking up the slack. The idea is that when the 'money runs out' the economy should already be functioning more or less normally, so that government spending can be scaled back; with growth, the debt-to-GDP ratio decreases so the level of relative debt falls.
Government basically acts as a safety cushion during a recession, because it is the only actor that can propel growth. It makes no sense for rational individual businesses or consumers to spend money at this time, but government can defy this - it can demand goods and services from businesses and distribute cash in the form of unemployment benefits or other social help which people then go and spend as well.

I can see we need to have a discussion about Demand pretty soon, maybe in a new thread. Since our posts are getting a bit long, I took the liberty of breaking it up into a few smaller parts, starting with this one.
The first issue I have is the assumption that the economy will be functioning normally as a result of stimulus. I am not at all sure that such would be the case, even at far larger amounts than what we've done so far, considering the debt we've already got. I know of no case where that plan worked, outside of the enormous amount of spending and the length of time we did it during WWII. We ended up with enormous debts after the war; we were able to pay if off then, not sure we could do it again. Didn't seem to work too well in 2009; why should we assume a different result if we tried it again?
[I agree... these are getting very long and I'll have to get to your second post another time

Well, the assumption might not be that the economy will function perfectly normal - only that, at an overall level, it's obvious that if businesses aren't hiring, and consumers aren't spending, as is the case in a recession, and if less spending leads to less hiring and less hiring to yet less spending,
some actor needs to revive (or maintain) the growth of spending, and the only actor who can do so is the government, because while rational consumers and businesses will want to save, not spend (despite the fact that on the whole it compounds the problem), the government is the only actor who can muster the rationale for higher spending - because if its spending drops in line with the rest of spending, there will be even less spending, and thus even less hiring, and thus even less spending, ad nauseum, and if such a thing continues it will be toppled or defeated at the polls.
In terms of spending during recessions, WWII is a particularly spectacular example but the same has been done in most recessions, only that these recessions were not as bad as this. Most of the previous few recessions have been during Republican administrations which used both tax cuts and increased government spending (both Reagan and Bush dramatically increased government spending and payrolls) to egg the economy on. Tax cuts are also stimulus because they imply more income and more expenditure on the goods and services that keep the economy going [though we'll get to why spending is, I believe, far more effective during recessions in a bit].
Whether this debt is repaid or not is important, but only secondary to the growth imperative. If growth is not restarted there is no way the debt will ever be paid. And if the economy shrinks due to massive government cuts (which it certainly would if the trillion-dollar-deficit gets closed), the level of debt will stay the same and will in fact be much larger and much more unpayable relatively speaking - and then the real debt crisis comes, as Europe has learned the hard way.
As for scaling back spending and reducing the debt burden, we did that too after the war was over. I'm not sure we could or would do that either, recent history suggests that politicians woukld rather keep spending more money than pay down debt.
I totally agree that politicians would rather keep spending money - because it keeps boosting the economy and increasing their chances at being re-elected. But it
can, as you say after World War II and in fact during Clinton as well growth in government spending decreased relative to the economy (the budget went from 1.4 trillion to 1.8 trillion over 8 years, compare to Bush's 1.8 to 2.8 trillion in the same time period - admittedly in many ways because of a Republican congress). It can be done, the problem of course is that fiscal hawks disappear when they're most needed: during good times. Booms are the time for austerity, not busts, because it compounds the problem. It is tempting for politicians to keep filling the punch bowl - that's when 'tea partiers' should come out; not in the middle of a giant recession.
In those days the US economy was the only game in town, most of the rest of the developed world was in ruins. They raised rates to exorbitant levels and got away with it; such is not the case today, there are other places where people can invest their money. BTW, do you realize that back then EVERYBODY paid taxes; the lowest rate was 22% for income between $0 and around $22k or so. I'll look it up later and edit this post. Edit: 22.2% tax rate for income $0 - $16807. Everybody paid something.
Well, actually not really if you think about it - investors are fleeing EN MASSE to traditionally safe US treasuries because the entire world is screwed right now. Investors are begging the US to keep their money safe and there's almost literally nowhere else to go or to put that much money. Debt only really becomes a problem, as we see in Spain or Greece, when people think you simply cannot pay back, regardless of what the absolute level is. Spain's debt is about 3.5 times smaller than Japan's (the US's debt level is half that of Japan), yet investors are fleeing Spain, not Japan (in fact they are flooding into Japan as a safe heaven compared to the Eurozone). This is a huge advantage for the US and it is being squandered; right now with the entire world economy in turmoil is
the window of opportunity in which the US can increase its debt level with virtually no consequences - there is literally nowhere else to go and it will continue to be lent money.
In your 2nd paragraph you seem to suggest that increased gov't spending is the only answer. Not true, first of all there's no evidence that redistributing wealth would result in more spending of all that money. I suspect that in today's environment most of that money will be saved rather than spent; I know I would rather put most of it away just in case I lost my job or had my wages cut. There are some countries that did cut spending, and got themselves out of fiscal difficulties. Sweden and Canada come to mind.
The bolded part is exactly the case for wealth redistribution during recessions. Poor and middle class people have a higher marginal propensity to consume than rich people and it's for a simple reason - if you redistribute money to people who don't have enough to pay for things they
need - they
will use that money to pay for things! You and I might be able to save the money - so we're not good targets to get more money. But if you go from $700 a month to $800 in income, you can be sure as hell you'll be spending 100% of that money. But as you climb up the income ladder you see that the richer you are the higher the proportion of extra income you will save, especially during uncertain times. The poor and newly-struggling middle class don't have that luxury - money given to these groups gets spent because they need to spend it, whether on consumption or deleveraging [paying down debt].
And there's only 2 ways you can pay for that extra spending: you either raise taxes on the wealthy or you borrow it, thereby increasing your obligation to service the debt. Since taxing the rich doesn't come close to paying for the stimulus, you're going to have to borrow most of it anyway. Don't know about you, but I have serious moral issues with putting that much debt on our children and grandchildren to deal with.
Well, increasing taxes on the wealthy is one option that would ease the burden - again, because the rich are saving, so funneling to lower income groups more or less ensures the money is spent. But yes, on the whole a lot of it would be borrowing, which would increase the debt burden in the short run but decrease it in the long run assuming that the higher spending accelerates growth and makes debt less relative to GDP (and it does considering government consumption is itself a component of GDP).
As far as 'saddling the children' with debt, I like the sentiment but I've never quite agreed with it in practice because there's really two options: spending can get slashed in the middle of a recession, plunging the economy into a depression, and leaving 'the children' with an indefinitely bankrupt economy, OR you can spend as much as possible to get the economy restarted, and, should it ultimately fail, default. A default is catastrophic in the short run but within a few years almost universally growth gets restarted, the same is not true of a prolonged imposition of austerity - compare Greece now to Argentina in 2001.
