We've essentially been through a war, though not one fought on our own soil (USA has been very lucky in that regard). A very large number of Americans have died or been disabled, the supply chains have been shifted a bit because of different priorities, and we're now struggling to get back to "normal". But like any war, a lot of people are dealing with PTSD at various levels and the whole thing is going to take a while to sort itself out. Not everybody is going to go back to the same career they had before, not every business is going to survive.
We are living in extraordinary times. There will be books and movies about this period.
