Found an interesting post here that I wish to archive for future reference; as it consists mainly of quotations, I don’t see this as a problem.

It’s been quite verified that the people who emerged from tenement housing were/are very, very often infected with a host of social pathologies.

See John B. Calhoun’s research on the deleterious effects of overcrowding on mice and rats, which virtually mirrors the effects you see on the crowded underclass in countries around the world:

“…the rats in Calhoun’s experiments developed social pathologies similar to the behavior of humans trapped in cities. Among the males, behavioral disturbances included sexual deviation and cannibalism. Even the most normal males in the group occasionally went berserk, attacking less dominant males, juveniles and females. Failures of reproductive function in the females – the rat equivalence of neglect, abuse and endangerment – were so severe that the colonies would have died out eventually, had they been permitted to continue.” –

“There was no shortage of food or water or nesting material. There were no predators. The only adversity was the limit on space.

Initially the population grew rapidly, doubling every 55 days. The population reached 620 by day 315 after which the population growth dropped markedly. The last surviving birth was on day 600. This period between day 315 and day 600 saw a breakdown in social structure and in normal social behavior. Among the aberrations in behavior were the following: expulsion of young before weaning was complete, wounding of young, inability of dominant males to maintain the defense of their territory and females, aggressive behavior of females, passivity of non-dominant males with increased attacks on each other which were not defended against. After day 600 the social breakdown continued and the population declined toward extinction. During this period females ceased to reproduce. Their male counterparts withdrew completely, never engaging in courtship or fighting. They ate, drank, slept, and groomed themselves – all solitary pursuits…The conclusions drawn from this experiment were that when all available space is taken and all social roles filled, competition and the stresses experienced by the individuals will result in a total breakdown in complex social behaviors, ultimately resulting in the demise of the population.” –

“…protected from disease and predation and supplied with food, water and bedding – they bred rapidly. The one thing they were lacking was space, a fact that became increasingly problematic as what he liked to describe as his “rat city” and “rodent utopia” teemed with animals. Unwanted social contact occurred with increasing frequency, leading to increased stress and aggression. Following the work of the physiologist, Hans Selye, it seemed that the adrenal system offered the standard binary solution: fight or flight. But in the sealed enclosure, flight was impossible. Violence quickly spiralled out of control. Cannibalism and infanticide followed. Males became hypersexual, pansexual and, an increasing proportion, homosexual. Calhoun called this vortex “a behavioural sink”. Their numbers fell into terminal decline and the population tailed off to extinction. At the experiments’ end, the only animals still alive had survived at an immense psychological cost: asexual and utterly withdrawn, they clustered in a vacant huddled mass. Even when reintroduced to normal rodent communities, these “socially autistic” animals remained isolated until death. In the words of one of Calhoun’s collaborators, rodent “utopia” had descended into “hell”” –
