Now, not knowing much about The Valley's history (other than the obvious), I'm wondering if these problems you speak of were caused by an influx of techies who feel entitled in the area. The glory of movies like "The Social Network" encourage ambitious young hackers like myself to move westward because of Hollywood-crafted fantasies, rather than necessity or convenience. Consequently, meritocracy is diluted.
Thoughts? These ideas are more from my intuition than anywhere else; I've lived in Boston from birth.
