How many of them need it?  If the rates are that high, it suggests that
authorities are now diagnosing milder and milder cases who would
previously have gone unrecognised.  ABA is a useful form of treatment
for some autistic children, but certainly not the one-size-fits-all
treatment it's often made out to be.  For many, and possibly most, of
those children, it just isn't going to be a
necessary/beneficial/appropriate treatment.  (My son almost certainly
has mild ASD, although we're still awaiting the formal diagnosis.  I see
no reason why he would benefit from ABA at this stage.)

All the best,

Sarah
