Seeing people maskless in the outside world is a shock because they live in a country that constantly tells them it is protecting then with masks, daily, or twice daily mandatory testing and draconian lockdowns where they might:
a) starve to dearth
b) burn to death in a building fire
c) commit suicide
d) climb out of the building and get beaten then disappeared.
In most places today the masses are an expense. Why would anyone care to maintain an expense?
