Before the modern system of mass schooling (whether private or public) came into being, in-home education, via tutors, tailored for individual childrens' needs was the norm for the aristocracy and the very wealthy commoners.

Is it a big surprise that we're starting to see inklings of that again, given the growing gulf of inequality in the Bay Area?

I'm sure it's wonderful if you can handle it logistically and financially. I do wonder, though, if hybrid approaches may be more accessible to the middle class.
