"in 9 months there will be a baby boom, entirely consisting of firstborn children"
In short, it seems likely people are going to have more sex when they are stuck at home.
OTOH, I know people with children who are going crazy. I don't they are encouraged to have more children.
I am going crazy, but my kids are also learning an absolute ton from having all this 1:1 attention from someone who is totally invested in them. I've seen big strides from each of them. Their character is really coming out.
I'm one to look for silver linings; this is surprisingly one of them.
Like Warren Buffett says, "From a standing start 240 years ago, Americans have combined human ingenuity with a market system to deliver abundance beyond any dreams of our forefathers...". There is nothing to suggest this is suddenly going to stop moving forward, even as we adapt to these new realities.
