I read the Wiki article, but it still makes little sense to me. Why does the government owe $10 trillion to debt instruments? Why would they borrow that much from a private organization, when they print their own?
More importantly, where does all of our currency come from, and how does that relate to national debt? I'm told the federal reserve produces money, but I'm not sure how that all works.
Here's another question to ask yourself: if the government prints its own money why does it ever need to collect taxes?
I'm not an economist or anything but my amateur attempt at understanding fiat currency (paper money that isn't backed by gold or silver, what we've had for the last several decades) is this:
In a dollar-based economy, there ought to be a dollar somewhere for each thing of value, right? But if dollars have to be backed by something like gold, there can only be as many dollars as there is gold, which is going to be a fairly fixed amount.
But new economic value gets created all over the place all the time - companies manufacture new goods from raw materials, technology advancements increase the value of things (just to make an example up - a Ford Model T might have cost the same as a horse to own but in many respects it has more value; goes further, faster, etc.), the value of real estate increases due to population pressures, everyone personally does work / provides services to their employer every week and gets a paycheck for it, teenagers come of age and enter the work force, and so on.
So with a gold standard, unless a country has a
really productive source of gold (like Spain had during the Spanish Empire) the economy expands much faster than the supply of gold does. So the supply of gold can sort of put some artificial brakes on the expansion of the overall economy. (Plus you get funny effects where each country wants to get gold away from the other countries and hoard it.)
In a country where a central bank like the U.S. Federal Reserve or the Bank of England prints the money as a fiat currency they're able to create new dollars to match the expansion of the economy. I believe that the primary method of doing this is that the central bank loans money to other banks in the nation's financial sector.
But they can't just print money willy-nilly; if they create more dollars than correspond to the total value of all the stuff in the economy the value of an individual dollar goes down. Whereas the cost of a gallon of milk was a single dollar at some point in the past, nowadays it's between three and four dollars (at least where I am it is.) If the government just prints as much money as it wants to you get runaway inflation as happened in Weimar Germany after WWI or during the last decade in Zimbabwe: a gallon of milk goes up to a thousand dollars, then ten thousand, then a million dollars... essentially, everyone collectively realizes at the same time that a dollar isn't worth anything.
That's why the U.S. government can't just print money to pay its employees and buy whatever it wants. The money it spends has to be represented by real economic value that gets transferred to government ownership somewhere along the line. Hence the government has to collect taxes or raise money in some other way, and when it doesn't raise enough it has to borrow money to buy what it wants. If we just printed money to pay government debt we would wreck our economy with runaway inflation.
As I understand it that's one concern about this recent government bail-out of banks - that there wasn't time or a practical way to raise "real" money to fund it, that the banks have essentially been bought out or shored up by the government simply printing money.
Another aspect of it to understand is that the U.S. government is in a very unusual position compared to other governments in the world: the U.S. national debt is denominated in U.S. dollars. We're able to get that arrangement because we're the most powerful economy in the world. So technically we
could print money to pay off the debt and the money we payed out to our debtors would become worthless as inflation skyrocketed and we would laugh at them and thumb our noses. We could only ever do that once, really. But most countries don't have that luxury: they have their own local currency while their national debt is denominated in U.S. dollars or euros or something, so they have no way of printing money that would pay off their debt.
[edit]One more thing: so when you ask how a fiat currency dollar can have value when there's no asset which backs it they usually say something like "the value of a dollar derives from confidence in the U.S. government." I think what this specifically means is people have faith that 1) the U.S. government is going to make sure that all debts denominated in dollars are going to get paid (both its own debts and private debts by enforcing the laws) and 2) the U.S. government is going to ensure that a dollar represents real economic value by maintaining the economy (keeping interest rates under control, fixing things like the financial crisis) and by not doing things like creating runaway inflation.⚛
