That assumes that a lot of people are not loosing money at the same time. The vast majority of the food service and entertainment industry being out of work will offset those for whom this is just an extra paycheck.
Inflation should have gone through the roof in 2010 as well, but all that got inflated was stock market (because the only place the money was extra was for the investing class).
True but vast swaths of the population saying home means a lot of people will not spend the extra money on things. Some will use it to pay off debt, some will save it, some will buy a little more and replace consumers who are pulling back.
One of the realities of modern life is that few Americans have a lack of things. The glut of stuff means the money supply is only one part of what determines if consumers will buy more of it. Even TP which has been hit by panic buying has only seen small increases in price, with the exception of the price gougers and opportunists, but that market will likely collapse in the near future as there is only so much TP a country can use.
