* Housing in the area makes vibrant communities difficult, thus encouraging isolation.
* Typical social dynamics within those companies encourage long job-focused hours, thus encouraging isolation.
* The old adage "power corrupts" is a sad truth inherent in human social dynamics. The above two factors encourage those disposed to predatory behavior to focus on the workplace rather than high barrier 'third space' settings like bars and clubs.
I believe one of the best ways of combating this issue (that isn't already implemented, if not adequately enforced) would be zoning laws that encouraged housing density to match economic pressure while still maintaining community nexuses to provide positive social interaction environments.
