About ten or eleven years ago I had a short discussion with Oliver North on his radio program about this very subject. Nothing seems to change much unfortunately. The croaking death of the MSM may help.
Years ago (almost 12 years) I read an article by Cal Thomas that made so much sense. He said the public schools weren't going to change unless they were motivated to, and they wouldn't be motivated to unless people starting pulling their kids out of the system "en masse." It was that article that motivated us to homeschool. Nothing has changed, well, that's not exactly true...schools have gotten worse especially in the area of pushing liberal propoganda on the kids.
Of course, the other side is that the home schooled children win all the prizes and a hugely disproportionate share of seats in competetive colleges. The Baptists were expected to withdraw their children from government schools by vote at their convention this week.
More schools will close, but many will remain. Suburbs are happy with their schools, and poor will undoubtably take whatever they can get.
