The longshoremen's union supported the Occupy shutdown, but were contractually obligated not to participate in the protest. Source:

Since almost everything else you said is anecdotal, it's hard for me to respond to, but your statement about the longshoremen, that's certainly wrong.
In general, the people that you are deriding and caricaturing represent the first wave of gentrification, and those people actually do make meaningful contributions to the areas they move into. Think of the excellent restaurants, concert venues, boutiques, bars, etc. that exist in Oakland now--that's first wave gentrification. Those people are also historically more aware of their surroundings and the culture that they are moving into and tend to show solidarity with the lower income residents that they are paving the way towards displacement for. On the other hand, the second wave of gentrifiers tends to dramatically increase the cost of living, rate of displacement, and tends to care very little about the plight of their fellow citizens.
The Google buses are a convenient symbol for economic disparity though, and I often wonder why Google doesn't try to do a real public works project instead of simply creating a segregated system of buses. Why not add wi-fi to public buses? Why not extend the light rail system into the valley? Why not donate a whole lot of money to a public mental health project so there aren't so many deranged lunatics screaming on public transit? If they did that, then they will have created a more comfortable environment not only for their own employees, but for the entire community.
