If we have hyperinflation, we will have not only that but also the destruction of our currency, as well as the loss of foreign investors of any faith in our "financial system" whatsoever. All the liquid wealth of this country will be wiped out.
You keep making assumptions that a hyperinflation will just be pushed year after year after year. There is simply nothing to back that up that assertion. Nothing that has happened so far, or is expected to happen, or that the government has any likelihood to do in the future, is likely to result in hyperinflation. In the long run the government, and the Federal Reserve system, is far more dedicated to keeping inflation in check than they are to let it run wild. They are even prone to excessive inflation fighting at the expense of their other responsibilities. That is one thing that happened during the Great Depression.
Maybe there will be inflation. In the long run there is always some. And as long as it is low, it's not really harmful. Even if it's temporarily higher, that's not a disaster.
Deflation, on the other hand, cannot really be combated by any tool available to the government. And long term stagnation is the best case scenario for what happens when you have deflation. Depression is a very strong possibility.
During deflation personal and business income fall. But loans are made in nominal dollars. What that means is that the real costs of loans go up as the currency deflates. And that means that more and more loans are forced into default, and more and more banks and other financial institutions will become insolvent.
With inflation, the real costs of loans declines over time. Which means that the loans can be more easily repaid. banks, unsurprising, don't like this. But the loans get repaid, and the banks stay in business.
Accounting is really unforgiving on this point. Either the loans are repaid, or banks can't survive.
Now in both deflation and inflation lending eventually slows, and then stops if it gets too much out of control. But lending can continue and banks can remain solvent with fairly significant inflation. It cannot with deflation.
The reason, in part, that the foreign exchange rate of the US$ has not collapsed, despite all the extra spending, is that the US has historically been pretty good at getting it's inflation under control compared to other nations. And there's really no reason to think that in the long run that we won't reestablish that.
I was just pointing out that U6 was available as well. Inflation is not necessarily easy to contain; Remember, the 1970's were a decade lost to inflation as well. It wasn't exactly the best. and the 1970's were not hyperinflation. Hyperinflation would wipe out the liquid wealth of the US. Put it simply- all SS trust funds, savings, 401k's, etc... ALL ZERO.
If inflation is too high for too long, assets denominated in constant dollars lose their value. But stocks will go up to match other price levels. There are a lot of reasons that inflation stayed high through the 70s. But sometimes these things happen, and nothing can be done about it. With deflation wealth is wiped out as well.
So the question becomes were do we stand to lose the least. And the way we stand to lose the least is to prevent deflation and depression, get the banks back on a sound footing, and get the world economy growing again as soon as possible. And just live with the consequences of whatever inflation we can't stop.
OTOH, in my more bitter moments, I can't help but think that people with the most saved dollars are responsible for creating this mess, so they deserve what they get.
