Historian Forrest White has documented what this was: a technique. Once city leaders floated the possibility of redevelopment, landlords stopped investing. Properties deteriorated. The deterioration was cited as evidence that clearance was justified. The slum was manufactured, then used to justify destroying the community that had, until the manufacture began, sustained itself. The look of natural decay hid the engineering of it — beguiling, cast as policy.
Guy Debord, writing the year before, called this management of belonging the spectacle — not images, but social relations mediated by images. You are not experiencing your social world. You are consuming its representation. The love the spectacle offers is always at one remove: you are connected to the image of connection, you belong to the image of belonging, and the representation is more vivid and more legible than the living thing it replaced.
This is enclosure applied to love itself — belonging contingent on legibility, the field converted into a managed arrangement where the price of admission is yourself.
Baudrillard called this the hyperreal: not false, but more legible than the real it replaced, optimized for the metrics the system can measure. You can get an answer faster this way than from a library. The answer is often right. What the system cannot do — stay in process, find the gap, produce the lateral leap from the oblique angle — is not in its metrics.
