Fred: Your analysis is worthy. The world population is not going to drastically decline regardless of what we do.
From my rather limited perspective, the management of Covid 19 has been mostly about hospital beds. If hospitals are overrun and can't do their job properly, more people are going to die. Covid was, is, and will be filling up hospitals quite fast.
We can argue the merits of the lockdowns vs. the economy or social psychology of the people. This is not an easy decision for politicians to make. I feel sorry for them.
In the meantime, those of us outside the decision making realm can help by wearing masks, social distancing, and limiting our social outings. All these reduce transmission. It does not matter if masks are 20% effective--that 20% is still reducing the transmission.
Think of the hospital staff these days working in these chaotic times. Wear a mask for them so they can take a break sooner than later.
But if one does not give a f**k about anyone else, then take off the mask and go to big indoor parties.
