Is this lead poisoning theory really any more proven than say, the access to birth control idea?

Young people tend to be economic migrants and the pockets of mass economic growth start in cities. They're also single and relatively poor so they live in multi-tennant housing near the downtowns where they work. As they get older, richer and more numerous (i.e. married w/ kids) they move out of the core. Cycle repeats with rising prices if growth is still there, or you hollow out the city and only the poorest remain. SF could stay like it is, or become a west-coast steel town, but it's unlikely to return to what it once was.

It's varies over time. With SV-style tech that hasn't been the case until quite recently. And, in the Bay Area, arguably the nexus of jobs is still in the South Bay. And this sort of situation is true for many other areas as well.
