Could America be saved financially/socially even if not all medically by $1 a piece masks

Wouldn’t we be much less anxious about going about reopening consumer markets (department stores, computer repair, jewelry etc.) if ourselves and everyone else were wearing N95 masks?  Ttalking theoretically -- understand numbers unavailable.

Could the US corona transmission rate drop below 1 if we all could wear N95s all the time -- lock downs or no?

We would for sure feel safer (even safe?) on airliners if all aboard wore N95s.  Virologist and NBC contributor Joseph Fair opines he caught the bug on the airplane even though he was wearing the best breathing protection because the virus entered his eyes. Of course if his fellow passengers had all been wearing his (presumably N95) level of protection the viral load of the air in the passenger cabin should have been negligible.

"To get technical, airplanes deliver 10 to 12 air changes per hour. ... Airplanes also use the same air filter — a HEPA filter — recommended by the CDC for isolation rooms with recirculated air. Such filters capture 99.97 percent of airborne particles."

Could America be saved financially/socially even if not all medically by $1 a piece masks -- flattening the curve in most non-restaurant style businesses all by themselves?  Could the airline industry be saved for $1 a passenger.  If so, time to stop talking theory and start manufacturing tens of billions of N95 masks?

PS. The model of N95 with an exhaust valve on the front does not protect others from our viruses.
