I think this ends up as a blip on the radar. i don't mean that flippantly, but we love our freedoms and the ability to do what we want. The american public is just waiting for some sort of "all clear" so that we can get back to doing what we did before this happened. Will some be more cautious than others, most likely, but the majority will go back to business as usual and not give the virus a second thought.
I think financially this will wake up a lot of people in terms of how they are not prepared to be without an income for an extended period of time. I think you will see more fiscal responsibility from a lot of people.
I hope you are right that it is a financial wake up call for those half of Americans that live check to check. Most Americans are poor savers. Hopefully we have treatments for this virus soon and a vaccine that allows this entire thing to appear as just a blip on the radar a year from now.
