Change is necessary. Here is an interesting article on the forces of supply and demand in the Bay Area, which have led to differing views on the pace of growth. I'm firmly in the camp that believes we need more thoughtful growth. Market forces are pushing at a pace that is overwhelming our infrastructure and our local government's ability to ensure quality of life is protected.
From the article "Three basic forces are driving the Bay Area’s housing prices upward: growth, affluence, and inequality. Three other things make matters worse: finance, business cycles, and geography. All of these operate on the demand side of the equation, and demand is the key to the runaway housing market." In Palo Alto, we've also had a near runaway office space market, with office densities and office locations not contemplated in the city's plan.
