Well, no, it's the problem of people with children with disabilities who live in that state. Most won't care.OK I get the idea how that could turn out bad in some states, but that's that state's problem.
Admittedly, I can look at it from a European point of view, and say "well, yeah, France doesn't get to decide how Germany takes care of its children with disabilities". Likewise, I can understand why Texans might not want Californians to butt in. Sadly, this will result in a lot of states just saying "screw 'm". As a first world country, I can see why you'd want federal minimum criteria that have to be met. But where that line is drawn is very much a political issue.
