While I think the issues raised are indeed valid objections I don't think specific individuals should be targeted to pay higher taxes to offset the cost of special education.
It seems like in trying to solve an issue we have taken it too far and created another separate issue (the funding) to replace it. That seems to happen a lot. lol. We should try to stop being so short sighted, but I guess that's easier said than done and all one can do it learn from experience.
