Here is a table from DDL. Look at how many school-age children have died from CV-19 in Minnesota. Zero, that’s right, zero. So don’t buy any of the crap about teachers being concerned about students health. And the research shows that children don’t actually spread much to adults. And obviously a lot of other diseases kill a lot more children.
What has happened is that children’s educational and social lives, and other aspects of their health, such as vaccinations, have been severely damaged, especially for minority and low-income children. Many poor children have just given up on school. If we care about our children, we have to cut this crap out, and squash the teachers’ unions in particular.
