I'd say that society does indeed have a place in the increase in mental illness.

Maybe this is a bit of a tangent, but there have been studies that show there may be a link between autism and nutrition. I wouldn't doubt such a connection seeing as how so many people live off of nutrient deficient processed foods. It sort of stands to reason that if your nutrition is off, then your body is going to have problems. It wasn't so long ago that autism was considered to be more rare. Now it seems like everyone has it and its the trendy illness to have, that is be "on the spectrum". I don't think that the spike in diagnosis rates is solely due to doctors being better able to see such problems in people. But yeah, this sort of fits in as society has modernized, our quality of food has gone downhill.
