Have you ever been here in Berlin? Baustelle (working sites) everywhere. Right now a huge complex for rich people is being built close to Alexanderplatz, while a Plattenbau (sort of prefab building) for good affordable housing is being built in front of it. There's a lot of space and a lot of socially oriented development. What you call, wrongly, Nimby-ism is purely the acknowledgement that we don't need to tear apart the fabric of social cohesion by letting random flying saucers (like Google's campus) land in areas which are not fit for properly welcoming them. There's plenty of places in still central but more depressed areas of the city where the Google Campus could have made much much more sense.
