I suspect the reductions in Govt funding to NDIS for autism will reduce the amount of labelling considerably.
Mankind evolved quite nicely with people "on the spectrum" long before there was a name for it. and it could be argued that we came out of the caves because of, not in spite of, people who have this way of processing information. It has certainly given us computers and the internet.
AFAIK there is no evidence based science that gives statistically significant results that a person who carries this label can't be trusted operating heavy machinery. I'm sure the rush of people getting themselves and their children labelled would stop in its tracks if it meant they would never be allowed behind the wheel of a car. So it is nothing but prejudice.
