the quote you dismissed
What's more, [Siegel] notes, an autism diagnosis gives parents access to costly educational services. "If I say, 'I have good news for you, Mrs. Jones -- your son does not have autism,' she'll say, 'No, no, I'm sure he has autism.' Parents are not always relieved.
"The more prevalent autism becomes, the more people get into the autism business."
