I think your response reveals how accustomed you have become to the luxury of having plentiful resources. You ask how it is good for anyone to not spend substantially more on students with special needs, but in many of the poorer countries of the world this attitude would be baffling. In many cases these students will never be able to contribute enough to society to recover what was invested in them. Hard choices have to be made that cause sadness, but unfortunately that's the way it is. If your country becomes less anomalously wealthy in the future, you may also have to make such decisions.
