I've never actually thought of any overall positive effects down the road for society, I'm pretty much just trying to get my kids the education they need and deserve, when they need it.
I guess that's what I meant. The effect of homeschoolers' actions (plus the programs I mentioned) might force the system to change anyway --- as a secondary effect.
I have a friend who argues that charter schools and vouchers (if they take off) could be strong thing for changing the public schools by forcing them to adapt or die. Home schooling and the gifted programs could all aid in that force for change (?).
