I don't have any hard facts, but I have been involved with a taxpayers group that is working to lower school based property taxes, and this is something we are seeing as a major expense. I also remember a book a while back that posited a position claiming that the reason for lower crime statistics was the fact that many potential criminals had been aborted. (This fact I doubt). While I don't believe at all in aborting unwanted or special needs babies, I realize that this is an argument that the liberal left uses to justify abortion. In other words, if a liberal claims that abortions reduce the number of handicapped children, then I would simply ask why so many more special ed kids are in school now, compared to before Roe vs. Wade.
Well, it's definitely worth looking into. Thank you!
