I have zero issue with closed schools without a plan to immunize the teachers within them. If these pols felt like opening schools was so important they would have immunized teachers first, they could have gone through that tier much faster than they did with doing the olds first. Don't get me wrong, I do think it the tiers were prioritized correctly.
Opening schools have become another political issue. Pubs don't want unions telling them to do. Mental health concerns are legit and also overblown, but absolutely legit, but that isn't a pandemic issue, mental health issues with school aged children have been issues ignored by Republicans, and Democrats, for generations. Using mental health now is simply a political shield, and you'll see this when the school year ends, we continue to make strides in immunizations, and school aged mental health will no longer be discussed and there won't be a single solution thrown at the issue, just like it hasn't been since the 1980's.
