Nowhere do I describe inflating away the debt. There is no reason whatsoever to do that. Zero. Nada. Zilch. I'll say this again: the term "US govt debt" is just a number that keeps track of the amount of money the govt has printed. A technicality that raises from the fact that the govt prints money not by issuing dollars, but by issuiong IOUs.
When a govt is the issuer of their own money, their debt does not follow the rules of your household debt anymore. This is the fallacy in the whole "govt debt bad" argument. You need to get your money from someone else to pay your debt, and you need to work for it. The govt doesn't, they can just print more money, and they do. The meaning of the word "debt" for you is completely different for the meaning of the word for the govt. Forget about the word and understand that these two things are completely different beasts.
You need to let this sink in.
Nothing about what I'm describing is leading to inflation, either. What I'm describing has been going on ever since the US went off the gold standard, and no one noticed. To reiterate my previous point, 95% of the money in circulation has been printed by banks, not the govt, and we see no issue nor hyperinflation from that. The govt could easily triple their output without a significant influence on money supply, and therefore, without any problems whatsoever. There will be a point where you start to create inflation, sure, but we are nowhere near that. And where you get runoff inflation is where your actual real economy is no longer functioning.
A part of this problem thinking is that people have not given thought about where the money that we currently have in circulation came from. There is no magical correct amount of money in the economy, and even if there was, we wouldn't have the faintest idea about it. And more importantly, the amount we currently have was not handed to us by God, the founding fathers, the aliens, or whatever. What we have right now, we just printed. That's it. We can print more, if we want to. In general, if you have deflation, you maybe want more, if you have inflation, maybe less, but the tools to fix the problem are much more dependent on the reasons of any such deflation or inflation. Like our current inflation problems, plain ol' corporate greed in the US and lack of cheap Russian energy in Europe. There's nothing about the amount of money in the economy in those problems, and there's nothing that the amount of money in the economy can fix about them. You first need to solve the real economy problem underneath, and then you can oil the machine by money.
In a more broader sense, govt money output is best seen as a counter-cyclical tool. Most importantly in a recession the govt should raise it's money output by building infrastructure - an investment in the future - and in doing so, create jobs and thus, customers. The new customers will spawn new companies that go to satisfy new consumer demand, and the economy will recover. This is how the New Deal was done, and the US has been coasting on that ever since, but the fumes are running out by now. These days instead we have austerity, because a recession is seen as an opportunity by the rich to buy up troubled assets on the cheap, so they pressure the govt to reduce it's money output to help further reduce the economy.
TL;DR there is huge leeway available between a recession and hyperinflation. We have been operating in that leeway since '71 without much of a problem, yet knowledge of the mechanisms of that operation have not really spread in the public.
