The "Public School Deathwatch" disclaimer is a great idea because they are collapsing. It is just a question of how long it will take for people to finally admit that the emperor has no clothes and how many more children will be harmed by the government school system.
One point that tends to be overlooked is that homeschoolers don't claim any expertise in managing or teaching a class of 25 or so students in a government institution. Teaching your own children and teaching the children of others in a highly regulated 19th century factory/school model are entirely different matters.
They'll never collapse because they are just another form of public welfare jobs.
#2 reason they'll never go away ? Because of all the parents who know that schools are in trouble but *their* school is just wonderful. These parents don't read their children's textbooks or sit in their classes to see or hear the drivel that passes as academics.
