A discussion of recent housing changes in Arlington, Virginia, an increasingly whiter and wealthier community, included this summary:
Perhaps the opponents are beginning to accept that their community is not, has never been, exclusively their own domain.
Who owns a neighborhood? In many American communities, the people who live there might feel this way. They expect to provide input and exercise some oversight of what happens in their neighborhood. They want to exercise control over their own properties and those around them.
But, they do not do this on their own. They interact with other property owners and also engage with local governments. These local governments typically represent a broader community and have regulations about what can and cannot be done in neighborhoods.
In this particular case, the residents are single-family home owners and they have money and status. Thus, they really expect to be able to control their surroundings and they have means to back up their interests. Zoning in the United States often privileges protecting single-family homes.
In the end, however, local government has the task of considering the broader interests of a community. These may or may not align with the interests of a neighborhood. The neighborhood residents can respond by not voting for these local government officials and it is relatively easy in a smaller community to express discontent with local officials. But, action may already be underway that cannot be changed.
Or, here is another way to address the same questions: if every neighborhood will change over time, who gets to street this change and/or benefit from this change? Those with means and vested interests will have their own perspective and goals while a broader community might have another point of view.
