One of the problems of these "studies" is there really was no study. Most of what you cite (CNBC) comes from a relatively small sampling of teachers who simply reported what they thought. There is no real verifiable data on most of those things. How was children's mental health assessed? What was the control group for the "learning loss?" No mention of grade level or geographical area is mentioned. No peer reviews of any of the studies. Most of this was simply aimed at getting kids out of the house so parents could go back to work so the billionaire class wouldn't have their revenue streams interrupted for long.
