I'm open to debate on this, but I must say that what Zen is saying here makes a lot of sense to me. The old-school conservative in me feels like it would be incredibly wasteful for Covid money to be used on things not at all related to Covid. Just saying.
You have to judge wastefulness by its real economic cost. Our popular media and political discourse does a very poor job of defining what waste means and how and why it's bad. Let me illustrate with an example:
1. The federal government suddenly decides to pay $1M to every person. Wasteful? No. Not in itself -- it wouldn't change anything in the economy. It's simply an accounting issue: money that used to be held collectively by the government is now held collectively by the people, though in an individual capacity. Now, if this made the government broke would have a lot of real effects, but that's a different story.
2. The federal government decides to pay $1M to every person who submits a sculpted bust of Donald Trump or Barack Obama to the WH. This is wasteful. Why? Because it requires the expenditure of real resources on things of no value. Labor will be in short supply if people are learning how to sculpt. Minerals could be in short supply, depending on what materials people would use for the busts. So much other stuff could have been done with the time, energy and resources devoted to bust-making.
So the question we want to be asking is: are these Covid funds being used to generate value? Normally, a government program is aligned with specific goals, and if those goals no longer exist, the program is wasteful. For instance, if we have a government program for tracking smallpox, operating it in a world where smallpox has been eradicated would be wasteful (I'm assuming that smallpox is permanently gone, for illustrative purposes). If we have a missile system to shoot down ICBMs, and nobody uses ICBMs any more, that would be wasteful.
But sometimes, government programs aren't so narrowly linked to specific goals. I don't know much about this COVID funding, but it seems that it's being used for general improvements that are salutary in themselves. If we are using COVID money to improve educational infrastructure, that's not wasteful unless we are doing something like gilding an already well equipped classroom. My understanding of public school infrastructure is that it's underfunded in a lot of places. Whatever -- the details aren't important to this more general point: sometimes government programs can have benefits that extend far beyond the initial purpose, and then their existence is justified by a different set of considerations.
A classic example: Radar. It was developed by the UK air force to defend against Nazi aircraft. After the war was over, the UK didn't have any specific use for radar. Does that mean it should have stopped investing in it? I don't think so. Radar is a wonderful technology. The Battle Of Britain spurred its development; but that doesn't mean its use case was so limited. This is a case of the government producing something of broad benefit. This is, by the way, a stylized example for a short msg board post. I know that radar had many military uses in peacetime -- for instance, early warning systems, detection of all sorts, etc. -- but it wasn't a **necessity** the way it was in 1940 and anyway the point here is that radar would be worth continued investment even if its military use vanished.
