Conversely, they tend to develop a state of anomy, callousness, apathy, contempt and disregard in relation to the welfare of others when it is not in one's own interest to support them. This second state, one of almost complete alienation and independence rather than interdependence, has been shown time and again in various situations.
 
One of the most notorious episodes involved the murder of Kitty Genovese in NYC [2]. In addition, the Kitty Genovese incident would seem to indicate that the more people that exist concentrated together, the less likely that individual worth has much merit. Congestion studies amongst many species bear this out as does, in general, crime rates in crowded VS uncrowded regions when variables such as socioeconomic class are factored into the mix [3].
 
The implications relative to urban settings and overpopulation, in general, are clear. As Larry Winn states, "Imagine a group of humans, indeterminate in number, confined in a place of fixed dimensions, wanting for nothing. They have plenty to eat, plenty of water, plenty of places to live, and only the dimmest sort of apprehension of a larger world. They might even think of "the outside" as a kind of malicious fiction perpetrated by malcontents. It's a circumstance not unlike the one "sustainable development" is supposed to create for us. Also, not unlike the universes of John Calhoun's rats. [4]"
 
He goes on to conclude in the same article, "...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."
 
At the same time, one could only barely suppose that such happenings as Kitty Genovese's type or as Larry Winn's description would have a high rate of prevalent to transpire in a small remote villages wherein personal relations are more all inclusive, intimate, relevant and indispensable for maintenance of optimal social welfare. With less people in a community, there tends to exist stronger intact ties across the board --even with strangers, who are merely passing through the environs.
 
In addition, I predict that, with material affluence on the increase in Bangladesh and elsewhere due to globalization of industries, many people there will become more like much of the US population -- self-absorbed, largely indifferent to the welfare of the poor, insular, impressed by wealth and signs of wealth (as exhibited by Hollywood starlets and major sports figures), driven to get as much for themselves and their families at the exclusion of others as could be possible, etc. This is largely because cultural values are predicated on whatever serves to maximally support life in a particular set of circumstances.
 
In other words, people will more readily commune with each other and share if these sorts of behaviors foster their own well-being. If taking as much for oneself with disregard for others does it, then this model, instead,  will be the one habitually learned and supported by the public at large. (Just as "necessity is the mother of invention," it is also the mother of behavioral patterns developing one way VS. another.)
 
As such, people tend to work together to get water, feed each other, and provide for other material needs in these societies wherein it is necessary for many people to work together as a precondition to fulfill common aims (without which doing they would all die). Opposed to this are the conditions wherein success is primarily and almost exclusively tied to personal fiscal gain rather than mutual philanthropy.
 
With this alternative in place, there is little loyalty to companions, employees, nor employers. Instead, the overriding concern is simply advancement of one's own profit and this aim, alone. Hoarding behaviors will, then, be on the rise, too. At the same time, the gap between the haves and have-nots will, also, enlarge. All the while, people will be seen not as having much merit in and of themselves as they will largely be viewed as expendable commodities -- as means to an end to add to one's own financial and other assets.
 
This being the case, the number of millionaires in the world swelled to 8.7 million. Meanwhile, is there any mystery about whatever most of them are trying to do rather than spread their wealth in service to humanity or improvement of the natural environment? No. Instead of promoting widespread benefits, they are, for the most part, striving to become billionaires (called "kleptocrats" in a related Wikipedia citation below as they are thievishly parasitic on the body politic).
 
Indeed, many are wildly successful in achieving this objective. 'The number of billionaires around the world rose by 102 to a record 793... and their combined wealth grew 18 percent to $2.6 trillion, according to "Forbes" magazine's 2006 rankings of the world's richest people [5].' In addition, their group has been expanding steadily. All the while they, also, command vast stores of resources (obtained through their purchasing power), manipulate their governments (through lobbies and other means) and control others (via military might and other kinds) to keep everything solidly behind their acts of racking in ever more dollars and possessions, including huge tracts of land and factories, for themselves.
 
The flip side to this situation is that US jobs are disappearing overseas to second and third world countries in which the populations are paid measly salaries of ~ a dollar a day for their hard work. Moreover, these laborers will get fired if they dare to complain about their income, work conditions, or other aspects of their jobs. Furthermore, they are, for the most part, easily replaced as there often exists the condition of large unemployment in their locations. Therefore, they'd better, meekly and gratefully, do as they're told by management.
 
Meanwhile, the goods that they produce are sold to eager consumers in first world countries, consumers whose own economies are crumbling due to a growing deficit of work at reasonable wages. For example, one in five Americans now lives on less than seven dollars a day according to fairly recent US census figures [6]. All the same, it is primarily the near poor, who give the most to charities -- not the middle and upper classes. It is because they are almost poverty struck and know the degree that being so can be horrendously grim to the point of being even life threatening.
