Because the lockdown is dissipating and investors are seeing a gradual but steady return to normalcy. This is not like a shooting war where infrastructure is destroyed and has to be rebuilt which takes lots of time.
I just did an experiment. I went to the grocery store, in Maryland which is still under heavy tyrannical lockdown. I DID NOT wear a mask.
I had one (a Trump 2020 mask) but kind of wanted to see if anyone cared. I even engaged with 2 or 3 employees.
No one said a word. It makes me think that most people are conditioned to go along with the charade but deep in their hearts, they know it’s a charade. They are done.
