I saw this up close in Boston (really Cambridge MA). In most American municipalities, neighborhood groups have enormous power to shape development. All development has to get approved by the city, and the city listens to neighborhood groups. Those groups can also petition a landmark commission to landmark a building making redevelopment much more difficult. And they can sue. Even when these tactics don't work, they're extremely time consuming. I've seen one court case drag on for years even though the people filing literally submitted briefs written in crayon. So it is often better to just settle with neighborhood groups, but like patent trolls, that only encourages them.

One issue is that in the US, we treat housing as the primary source of wealth for middle class people. So everyone is expected to be a homeowner. A world where the price of your primary wealth asset is rising is good! And a world in which its value is flat or falling is disastrous. And so local laws get shaped so as to keep housing prices high; in practice that means choking the supply of new more dense housing. After all, any change might harm the value of your home!
