I think we need to start with the flawed premise implicit in the title of the article - that only public school union drones can be "teachers". Getting rid of the education establishment doesn't mean a world without teachers. It means a world without bureaucrats telling us who can and can't be a teacher.
I agree, at least as I understand what you’re saying. My ultimate ideal isn’t individual homeschooling. I’d like to see technologically savvy private schools in which parents are heavily involved - a coop model, if you will.
This is especially so for Christian education. I think the church as a covenant community should come together and develop such schools whenever possible. This would be a great help to single moms, parents who can’t afford to homeschool, etc.
Teaching is a noble craft, profession, calling, etc. But I do think the current model is neither desirable nor indefinitely sustainable. Have you read much of Instapundit’s stuff on the higher education bubble, for instance?
