I was talking with one of my customers on Thursday about exactly that. She said pretty much the same thing, that if there was a shutdown of a short period earlier, it would have likely been over by now, instead of getting close to a year of this **** already.
Even my former professors and school mates said the same thing about flattening the curve. I can't say how different everything would be, but I honestly believe we would at least be on the tail end.
