It would at least appear that children from wealthier families are being diagnosed with autism at a higher rate. Perhaps pollution/nutrition is actually a dead end, or maybe autism is less likely to be missed in the children of wealthy parents, or perhaps diagnosis is more subjective, enabling doctor-shopping, and there are perceived benefits associated with a diagnosis. It would be interesting to compare the rates of autism diagnosis amongst the children of teachers and psychologists compared to lower/middle/upper classes at large.
