Here's a thought experiment regarding schools

6. Even with a vaccine

Companies and institutions are going to figure out that they can get by much cheaper with folks working/schooling at home. The business doesn't need the big office space with lots of cubes, furniture, break rooms, conference rooms, electric, heat and maintenance with all the associated costs when a smaller shared space office area can work just as well at much lower costs and higher productivity. School districts will come to the same conclusion over time and it will be cheaper to provide spaces for labs and some functions but most learning will be done at home or in small groups of students. This was all coming anyway, the pandemic simply compressed the time frame.
