I think homeschoolers should be out there beating the drum. Their success shows up the failure of the public school system. If I could afford to do it, I would homeschool my kids.
The public school system in this country highlights it's own failures quite well on it's own. You do not lead successfully by tearing others down in public, especially when the public already knows.
Most teachers like homeschooling but keep it quiet. They know the score.
The education whores out there in the public system need to get the slow cooked frog treatment. If you turn the heat up too quick, the frogs will jump out and escape.
4% per year growth is just perfect. By that time the universities will have lots of homeschooled kids graduating and taking jobs teaching, administrating, and steering policy.

If you can afford to be at home - the rest is not that expensive. You can get tons of materials for free.
