The Public Housing Experiment | Boston Review: Decisions and developments from 1950 to 1970, Shester argues, accelerated the physical deterioration of public housing and increased the concentration of troubled families living there. Limits on government maintenance funds, like the limits on the original construction costs, hampered the housing managers. And because of imposed rent ceilings, local housing agencies could not get the funds sufficient to keep up repairs by charging tenants. Physical dilapidation followed.
At the same time, tightening the requirements that housing be provided only to the neediest families meant that stable working-class families, once part of the mix, were gone. The renters became increasingly and exclusively the poorest and most troubled families. Their growing concentration in dense (and tense) settings compounded the problems of order. By 1970, public housing projects had gained their nightmarish image. Pruitt–Igoe (and others) came down.
