"it's clear that homeschooling is the only way to go"
Whereas this can be true, it requires a committed, and educated parent with the available time. Therefore home schooling is realistic for only a small percentage.
First of all, it does NOT require a "well educated" parent. I homeschooled my own kids for years, and several others over the years, and I never graduated from high school. The need to be "well educated" is a total, complete myth. A good friend is homeschooling her kids, and all she has is a GED.
What it requires is the determination and interest to do it. Period. If a parent sees the need to save his or her child from the gaping maw of public school depravity, he or she will find the time and means.
It is realistic only for a small percentage only because a small percentage want to. Where there's a will, there's a way.
