I can correlate the rise of autism with the advent of deinstitutionalization too. We used to remove schizophrenics and bipolars from the gene pool. Now we all but openly encourage them to reproduce. Is it any wonder the country seems like it has gone crazy?
that might account fpr a small fraction
not enough to be the real reason
we have a declining birthrate and a high abortion rate
relatively speaking, almost all kids are getting a lot of vaccinations versus the much, much less chances they inherit any mental problems from parents
When did we do that? For a brief period in the 20s?
