Is the US Actually Inflating its Debt Away?

Is the United States currently being successful at inflating its debt away? Well, it depends on who you ask. If you look at standard economics, it would say that the government can borrow money. And then when it spends that money, as long as it spends it in the right way, that's going to stimulate economic growth. And then that economic growth will result in more tax revenues, meaning that that debt paid for itself, and then some. One of the byproducts of this is that prices go up along the way. And so many people say that the government can just inflate its debt away, and that's why it chooses inflation. But we get into a problem with economies when the public debt exceeds 90% of GDP. So where is the United States and where is it in the cycle of trying to inflate its debt away since it's got a lot of debt and we've got a lot of inflation. Which one is winning?
