I do not think that American public education will survive the current war upon it in any form like the system we knew in the past half century.
One cost will obviously be in the refusal of good students to go into teaching. The slow step by step improvement in the status of teachers, their salary improvements, their benefits, their job security via tenure, etc., are being ended in many states. Skilled teachers now employed will have their standard of living cut and their retirement benefits, the pensions and health care, scrapped.
There is more and more movement toward home schooling of children and toward private schools. With the introduction of modern technology into the educational process, I think that school classrooms as we have known them will be phased out. Parents will no longer be able to use schools as babysitting services and will need to provide other means (if they choose education for their kids at all) to educate their offspring. I think there will less effort to educate kids in a variety of skills and subjects. Instead, parents will select certain "tracks" that they want their children to follow. Many will not get training in literature or writing skills. Many others will not get math instruction. Science, so odious to so many, will be in the curriculum of many fewer.
I believe in the next 20 years we will see the abandonment of many more school buildings. There will be no need for them.
