Natural immunity is another name for natural selection or survival of the fittest. Unless buboils appear or cannibalistic zombie-like attacks occur no one will pay attention. Isolating people in hospitals to await death alone takes all the drama and burden away from the public. Americans do not react until you hit them in the wallet and know little of nation-wide war, famine, pestilence, holocausts, or pogroms. They rather attack each other about masks or no mask mandates, statues, street names, political correctiveness, political and ideological hatred, demogogues, fake news, etc. Americans do not need an external enemy, we are our own.
