Why the chronic deficits? It still smells like the old "JOBS! JOBS! JOBS!" babble in disguise.
I'd like a common-sense non-babble answer to the question: 
Why do we keep running these deficits every year? I believe the following answer is babble-nonsense, but it's difficult to determine for sure. Is there a way to answer the question without the jargon?
I find it difficult to believe that the reason we're running up these deficits is in order to 
stimulate savings:
	
		
	
	
		
		
			
	
	
		
		
			You seem to be saying we must have budget deficits or else there is no savings. Which is false, contradicts history. We have had both savings and balanced budgets, simultaneously.
So what's the real reason why we have to run deficits? It's not the reason you're giving.
		
		
	 
The domestic and govt sectors can both be in surplus if there is a trade surplus.
		
 
		
	 
OK, assuming that makes sense (I'm not sure it does), still, who cares whether we have the "domestic" sector in surplus? Let the domestic sector do whatever it's going to do. Meanwhile, why can't the government run even, over time, having some surpluses and some deficits, offsetting each other?
And meanwhile, who cares whether trade is balanced or not? Let there be a trade deficit if that's what happens. All we should care about is not running up government debt. Private debt will take care of itself. Stay out of debt if you want to, but if private persons or businesses choose to run up debt, that is their private choice. Whatever, it is not good for the public to keep running up debt unnecessarily. You're giving no good reason why it should keep doing so.
	
	
		
		
			We do not have a trade surplus.
		
		
	 
We had mostly trade surpluses up until about 1960-1970. During most of that time we also had budget surpluses, in the 1800s and early 1900s, with a net debt, but no need to run up debt other than to pay for war. And who cares whether during that time we might have had some private debt?
I don't believe you that there must necessarily be high private debt if we have a budget balance and open trade. Your scheme seems designed to insist that we MUST always run trade deficits AND MUST run budget deficits, in order to  insure that the private sector does not bankrupt itself. Or some such theory. Do we have to take this on faith? 
Why don't we just experiment. We CAN balance the budget (over 3 or 4 years, getting it down) if we choose to. Nothing prevents that. Why don't we just do it, then do free trade and let the trade deficit do whatever it wants to do, and also let the private debt do whatever it does. You're saying the sky will fall? Why? 
	
	
		
		
			
	
	
		
		
			What's so great about 21 trillion debt and 300 billion annual interest on the debt?
		
		
	 
Issuing debt with deficit spending is a choice; if you don't want to manage reserves that way or provide corporate welfare, then don't issue debt.
		
 
		
	 
Which means we reduce spending and increase taxes -- that's the choice we have to make to stop issuing so much debt. Why shouldn't we make that choice, to get the deficit down? Regardless whatever consequences some theorizer says it leads to? Why don't we do it anyway?
	
	
		
		
			As for the $21T, it's a residual, like say the total money you've spent in your lifetime. What's the significance of that? Answer: none.
		
		
	 
So then let's stop doing it if it's not significant. Why run up all that debt which runs up future costs which future generations might be unable to meet, if there's nothing significant about it? If it serves no purpose, then let's not put all those obligations on future generations who might not be able to pay it. What is the need for this insignificant unnecessary debt which will damage future generations if those obligations cannot be met or if the lenders stop providing the loans?
	
	
		
		
			
	
	
		
		
			OK, so again, why are we running constant deficits and running up this debt, beyond 20 trillion, heading to 30 trillion? Why do we keep doing this if there's no need to?
		
		
	 
In order to satisfy the savings desires of our domestic private sector and our trading partners.
		
 
		
	 
Forget their "savings desires"! Let's stop doing it if the only reason is babble about someone's theoretical "savings desires." Let whoever is worried about their "savings desires" worry about it. Why should the taxpayers pay for someone's private "savings desires"?
I don't believe you that this is the reason we're running up these deficits. Why should I believe such jargon?
	
	
		
		
			If you want a society without savings, then fine, tax it all back.
		
		
	 
It's only jargon. Don't tax anything "all back" (whatever that means). Just increase taxes and reduce spending as needed to balance the budget. And let "savings" take care of itself. I believe that "savings" were OK in the 19th century when we didn't have these excess deficits. Are you saying no one ever saved money in the 19th century?
Unless you can say something of substance, this sounds like jargon only to justify the high deficits. And I believe the purpose is to "stimulate the economy" ("create jobs") rather than this jargon you're giving here.
	
	
		
		
			But to date, we want people to save. And we want our trading partners saving dollars.
		
		
	 
I don't think "we" or anyone gives a barn door about that. People will save if they want to. They don't need the U.S. taxpayers to keep running up trillions of debt in order to give them a reason to save. And if these excess debts are causing some extra savings that wouldn't happen otherwise, maybe those savings are unnecessary. Who says we need them? 
	
	
		
		
			
	
	
		
		
			No, that's a phony correlation. In the late 90s we had balanced budgets -- lower deficit down to zero -- and yet the trade deficit increased at a faster rate. Which disproves the theory that trade deficits cause budget deficits.
		
		
	 
The late 90's govt surpluses caused a recession in 2002.
		
 
		
	 
OK, now you're making some sense. The purpose of deficits is to "stimulate the economy." The excess spending and lower taxes causes some extra jobs. Why didn't you just say that in the first place:
The purpose of government deficits is to CREATE JOBS!!!
We don't need all the excess jargon and babble about the need for "savings" etc. It's just about 
"jobs! jobs! jobs!" -- and that's all there is to it.
	
	
		
		
			The private sector borrowed enormously during this time to invest in dotcom business and y2k. Much of that investing went bust, . . .
		
		
	 
And much of it made us all richer and was good. And the bad part was paid for by those who made the bad investments. It was a genuine boom that then ended.
	
	
		
		
			which is how the private sector deficit spends.
		
		
	 
But the surpluses did not cause the private sector to make bad investments. Some investing goes bust, other investing generates benefit = profits = wealth. The bad investing was not caused by the government trying to balance the budget by increasing taxes or reducing spending or benefiting from a boom and receiving higher revenue which it uses to reduce the deficit. So why shouldn't it do the latter, without running chronic deficits?
So, nothing about the good or bad investing gives any reason why the government should run deficits. Why shouldn't it just try to run balanced budgets over years, with deficits offsetting surpluses?
	
	
		
		
			That spending drove the govt into surplus, but without lower taxes or increased govt spending, it couldn't be sustained. And wasn't.
		
		
	 
No, the reason it was not sustained is because of waste and bad investing. And artificial deficits to try to sustain it would only sustain the BAD investing and waste. But the good investing will sustain itself without any government deficits to prop it up. Why can't the good investing sustain itself without lower taxes or increased govt spending to sustain it? Who says it cannot? How do you know? How do you know it's not just the BAD investing which is unsustainable?
You're insisting that we MUST run those government deficits for some purpose, but the only purpose you can give is to sustain BAD investing and "creating jobs" and "stimulating" the economy even if it's all BAD investing and BAD spending and phony jobs and phony "stimulus" for the sake of goosing the economy or getting it "humming" etc. just for the sake of the humming itself, the activity, the boom-boom smokestack banging clanging noisy robustness of the economy without anyone really being made better off. Except the "job creation" for its own sake, jobs for the rabble, to get the riff-raff off the streets -- this is all your jargon ends up saying, behind the code language about "savings." 
You're not giving any legitimate reason why we MUST run these deficits. You're trying to articulate it without using the slogan "job creation" and "stimulus" etc. But what other meaning is there to your "savings" rhetoric, except the same old "jobs! jobs! jobs!" babble?
