I made the point that homeschooling is, on average, superior in practice to public schooling, and I posted a link to research reports. The evidence from those reports is not "subjective." And yes, with that evidence, I am criticizing public schooling and saying that it is generally inferior.
Sure. Homeschooling is basically tutoring. It allows each student to receive personalized attention. If we paid to have each student in public schools taught by their own individual teacher, you'd get similar results.
It's apples and oranges. The public school system is like a factory, homeschooling is an artisanal workshop. Homeschooling is a good way to educate a few kids, but it will never be able to be applied to the population at large.
I'm looking at the results. The vast majority of students in this country go to public schools and yet, Americans are generally decent, religious and productive. I think the public school system, despite its faults, is generally succesful in this country.
