Unlike polluting industries of old, billionaires want to live next to their modern day tech factories. Thus their headquarters are a short drive away from their minimum 3 million dollar ranch homes in Palo Alto, their town councils demand low growth to keep the traffic down and the feeling suburban and all the worker bees must commute in from someplace uglier where poor people may live. Seriously, this is why all this is happening. There is no other reason. Google is attempting to remedy this problem by building compact quarantined worker bee colonies that won't impact the multi-millionaire enclaves that management cherishes.
