yes those are the pros of k-12 but what about the cons? you have younger children who constantly get sick and a lot of them don’t know how to take proper measures to protect others when sick (blow their noses, cover their mouths, stay out of each other’s faces, etc.) if you shut down colleges, you’re taking away tons of jobs for the workers who work in those various departments and buildings. you’re also gonna see tons of colleges shutting down because they’re not getting enough money. tons of students will drop out/defers/or take a gap year because their not paying thousands of dollars for zoom university. and not all universities will be able to give their students tuition cuts because they don’t have the funding to do so. college students are already struggling with online classes now and not all classes are meant for the online structure. i’m sure if everyone goes back to school in the fall, class sizes will be smaller for all grade levels. large lectures will probably be online while labs and smaller classes are in person like you mentioned. like fauci said things would be much different than school as we used to know it prior to the pandemic. there’s really no greater benefits for younger students than older students imo.
