It's said without (much) judgement. In the abstract, it seems exactly right to spend on it. But the reality is it a) very expensive and b) very disruptive. As some siblings mention, you will often have a class with 3-4 adults, only one of which is a teacher. And then several students who (through no fault of their own) can barely hold it together. For the 90% of kids in class, this is not helpful. And distributing it amongst many classes vs a more centralized special ed delivery system compounds the cost. We have aggressively used the school system as a distribution point of social services. Again, this seems logical. But this takes focus away from what the main intent is for the school system. There are pros and cons to this approach. I don't exactly know the answer, but instead of blaming administrators or teachers, we should be looking at what else we are asking schools to do besides educate. I know personally that the principals and superintendents spent less than 20% of their time thinking about how to make education better for the 90%.
