"The major challenge to neighbourhood, as a demographic-physical construct as well as a viable social network, comes from organizations and institutions (firms and bureaucracies) whose routine functioning reorganizes urban space. The stranger to fear may not be the man of different ethnicity on the street corner, but a bank president or property management executive far from view.”

From Logan and Molotch.

My prof used to say something similar around how the person to fear is not the individual suffering from mental health illness on the corner but the executives in their big shiny buildings. This is why it's always important to be able to read the power dynamics of a community through the lens of who suffers and who benefits.
