It probably isn't as fast as other production lines, but I could probably make 2 masks per second, and if I brought in night workers, that works out to a million masks a week. Not much, but profitable if I could sell them at inflated prices, but not at regular prices.
I don't though, because I don't have the contacts to be able to sell them. And anyway, I'm scared of liability if my masks don't work as expected.
That equipment will sit idle if coronavirus spreads to my bit of the world.
