If you think it wasn't that bad, you must be from a privileged household, and haven't paid attention to the data. Children, especially low-income children, have been devastated by remote learning.
Remote learning was a disaster for my family, and we have great internet with many computers, and a father who could troubleshoot all the problems, and tutor them some of the time. I cannot imagine what it was like for low income families.
