These questions are useless unless they concede there are vastly different effects for different people.

For every 1 kid who was miserable and depressed at home, there are X kids utterly relieved they could escape the prison like environment of school.

For every adult suffering from isolation of WFH, there are X who had the most productive happiest times of their life.

For every 1 who got laid off and experienced misery, X realized they were so much happier staying home and tending to family.

Introverts finally had the world shaped to their personality for a brief moment.

But I guess all that matters in the end are gross averages.
