Alright, look, given the direction of this discussion, I got to pop thought bubbles. Despite the many valid angles for debating the U.S. deficit, controlling and reducing it will require a phased approach. This involves balancing tax increases, spending adjustments, and policies promoting economic growth over [insert the amount of time needed here]. However, this will NEVER happen because there are too many conflicting interests from players with different agendas, both domestically and internationally.
Every time the discussion about the U.S. deficit comes up, I can't help but shake my head at how futile it all is.
Deficits are completely irrelevant. No serious economist cares about deficits as a problem in their own right; They are an accounting tool that provides just one of many data points to help understand which way things are trending.
Politicians love deficits, because they are something that the voters can be depended upon to become terrified by. People imagine (or actually are in the position of) owing a huge sum of money, and how horrible that would be (or is); And they genuinely believe that the national debt is the same kind of thing.
It's not.
At all.
If your worry is how the imbalance between taxation and government spending is affecting (and will in the future affect) the economic wellbeing of the country and its citizens, the size of the national debt, and of the budget deficit, is of far less importance than the rate of inflation, GDP growth, unemployment, and the foreign exchange rates against other major currencies.
And, of course, neither side of politics cares about deficits except as a tool to bludgeon their opponent.
To reduce a deficit, you must cut spending by more than you cut taxes; Or increase taxes by more than you increase spending. But neither party is interested in that.
One party pushes for tax cuts as though a cut in revenue will force a reduction in expenditure (it won't); The other wants to increase spending, but not increase taxation (at least, not by the same amount), which (if the spending is appropriately targetted) can be economically sensible, but drives up debt.
The problem being that Joe Lunchpail cannot accept the idea that it is economically sensible to drive up debt. But it can be, even for an individual. It makes sense to borrow money to invest in future income growth.
It makes even more sense to do that if your future income isn't constrained - if you cannot grow old, will never retire, are effectively immortal, and have a huge diversity of income streams. People are never in that position, but countries are.
Deficits are a red herring. They are one of the least important indicators of the merit of a policy platform.
Taxes are necessary to maintain the value of the currency. If the inflation rate is low, and foreign exchange value of the dollar is not collapsing, then the balance between taxation and spending is about right. Attempting to target zero deficit, or worse, to target a surplus in order to reduce national debt, are stupid (and futile).
A successful economy is one that has growth that outstrips inflation, and whose currency holds its value internationally. Debt and/or deficit are irrelevant to these objectives.
Controlling or reducing the deficit doesn't require any approach at all; It is an objective without merit. Nobody's life will in any way be improved by "controlling or reducing the deficit", and anyone who pledges to attempt to do so has no business anywhere near policymaking.
Look after GDP growth, inflation, and unemployment, and leave the deficit to do whatever it does. By definition, if those three things are doing OK, the budget deficit (and the national debt) are not a problem, no matter how large they might be; Their magnitude will roughly reflect the growth rate of, (and size of, respectively) the overall economy, adjusted for foreign trade.
Nobody will ever demand that the USA pay back her entire national "debt"; And there is no sum denominated in US dollars that the USA could ever find herself unable to afford to pay.
You needn't worry that you will come back to your nation one day to find that the baliff has stacked all your furniture in Canada, and changed the locks.
