Teachers are the ones that have been sitting there for years preventing as much shit as they can from getting on the kids. My mom was a teacher for two decades and I can't tell you how much time and money I saw her and her coworkers put into things like classroom decorations, basic school supplies, textbooks that weren't a decade out of date, and even food and clothing for struggling kids.
Can you imagine beginning Kindergarten as a 5 year old this year? At least many of these kids have grown up around more technology than I did, I'm not sure I had even seen a computer when I was 5. I didn't have one at my house until middle school. How are they supposed to navigate online classes when they can't even read?
The main benefit of school at that age is learning to interact appropriately with your peers and teachers. Hopefully the younger kids are more resilient and adaptive than I'm giving them credit for, because I can't imagine it being anything less than frustrating and depressing for them.
It's no different than it's always been. All of the hard work, planning and preparation has been on the shoulders of teachers for as long as I can remember. They've never had much guidance from leadership, which is often nothing more than a target grade their students have to hit on a standardized test. Up until now the status quo has been fairly consistent, so teachers have been able to informally provide guidance and leadership to each other. Now that things are taking a massive left turn, what is supposed to be the actual leadership is being exposed for what it really is.
