Addendum: I posted this fully understanding how unpopular it would be with this crowd. If we ever get hit with a a more fatal and contagious virus this may be our only way of preserving life. And as things stand with our industrial meat processes I suspect we will have more viruses to contend with.
It is not this simple. You can't, in our current system, shift wealth that readily and quickly. Even if you could, how would you approach possibly selling this in a democracy? And assuming it was feasible, and we could get popular support for it, how would it be implemented? Rationing cards? Government ran food stores?
This is NOT the Spanish Flu. It is very different in its behavior. There is currently no evidence to expect a more deadly, virulent second wave. Please remember that the Spanish Flu was anomalous because it had a more deadly second wave. Almost all viruses, as a function of evolution, become less deadly over time.
And this ignores all of the vast improvements in our understanding of sickness and hygiene, our availability of clean, sanitary conditions etc. Hell, even the change in density between 1918 and 2021 is massively changed.
The Fed seems to be doing just that

As for your claim to a lack of a second wave, I'll have to defer to the experts on that. I'm looking at a historical case for a worse case scenario which I think is prudent to consider.
