I suspect that a lack of adult attention in the first three years of life is a principal factor in the rising autism rates we’re seeing in modern economies. This would explain why autism seems to “cluster” in upper class homes, where the parents work nonstop. Upper class parents don't necessarily need to work non stop, and when they do, they can afford to have an adult give their kids attention. To make this claim, you have to show that upper class parents neither give their kids attention nor hire a nanny/au pair/have a grandparent looking after their kids.
