In my state the **average** private school tuition is under $4,000. This includes even the ***most*** exclusive private schools in the state.
So... A **excellent** private school in my state is well under $4,000 a year. Many of these private schools accept, and do and excellent job with, children with the usual disabilities and non-English speaking children that are commonly found in any neighborhood government school.
Obviously there are children with catastrophic disabilities, and these children are very expensive to educate. In my opinion, catastrophic education expenses should be part of all children's health insurance, since much of the expense occurred in educating these children is really medical in nature. For instance, are expensive hearing aids, sign language interpreter), or nursing aides for the severely retarded, really an educational expense? I would say it is a medical expense. (However... Health insurance is really a different topic.)
And you figure the average poor person pays that much a year in sales taxes that go to the school system?
