Homeschool and private schooling advocacy is driven at least as much by a desire to control curricula (usually fundamentalist christian stuff, but sometimes crunchy lefty stuff) as by a concern about the general quality of public education.

Is homeschooling really bigger than "homeschooling", like Montessori ?

The article says: "Some families wonder if the shutting of the schools is related to his D.E.I. retrenchment." My comment is directed towards: is basic education and child safety a D.E.I. matter (which in some political views are frowned upon)?

Serious question: where is this spending going? Also other commenters mentioned the increasing public spending on schools, with failing results. I keep hearing and reading stories about teachers having to buy their own pencils or bringing some food to school... is this a similar situation like the US health insurance system?

Partly. There do seem to be a lot of administrators.

Part of it is also schools spending millions on sports facilities that only benefit a small portion of the students. 99.9% of whom will never play a team sport again after high school. My own kid’s school just did that. Meanwhile they don’t even have a pair of $200 choir mics so parents can actually hear the school choir singing in the auditorium.
