Masks are not complex. It does not need to be an N95 certified mask to significantly reduce respirated droplets. You would be surprised by the ingenuity of entrepreneurs, but of course, this thread is not about logic but instead about jealousy of others' abilities to profit in a way that some people think is unethical, despite the fact that it would undeniably result in more masks to combat this crisis. In reality, most of the people with your viewpoint cannot envision themselves scrapping together something and pivoting their entire business on such a short time frame, and they share the relatively common personality trait in which they then don't want others to succeed where they do not.

> factories can't be retooled overnight, and people die in the meantime.

Of course the masks aren't hitting shelves the next day, perhaps two weeks before meaningful production increases. What a pointless statement -- the crisis won't be over in two weeks, and this same principle would have held two weeks ago, or eight. And then you would blame people dying on the entrepreneurs retooling to create masks? Another pointless statement if that is not your intent.

This is a marathon, not a sprint. A normal retooling for an auto manufacturer appears to take 8-10 weeks.

They should be in time to save a lot of lives.
