If you make the effort to make the articles genuinly interesting and informative, then there is very real possibility that you can get some genuine traffic from the article.

One of the beautis though is that a good article can get syndicated and thus you can double, triple etc the amount of organic traffic and number of links from the one article.

Article writing is a long term SEO thing though so you have to be patient.

From a marketing point of view, a well researched and written article can reach the top of the search engines for long tail phrases. So, title your articles similar to long tail phrases that are provided on WordTracker. Don’t guess what people are searching for, find out what they are searching for and tailor your writing around those subjects.

The traffic will still be thin but the visitors will be targeted and those are the ones that convert.

As for the social pressures, that is a little bit different, yet places like Hong Kong and Singapore have a far greater population density than we do and with comparatively less crime. I suspect that drugs and a generally undisciplined sense of freedom, a sort of anarchy that anti-social sentiment that hip-hop entertainment seems symptomatic of, are a major part of the social maladjustments.

As for the moving of the population towards the west and east, the major business magazines like Businessweek, Fortune, and the Wall Street Journal have been telling us for a couple of years now that people are discovering that it is much nicer and cheaper to live in places like Iowa than in that big city that essentially stretches from Washington DC to Boston or the big cities that ooze far beyond the traditional confines of San Francisco, Los Angeles, and Seattle. I lived in southern Arizona and had a boss who moved from the Los Angeles area for a contract the company took. He sold his middle class house and muttered about how he had to buy a veritable mansion in order to not have to pay a bunch in taxes because of the price differentials (his over a quarter-million dollar house was about the same as stuff then selling for around 70-80 thousand).

In short, we can still absorb more people if we had to, but, as you observed, we need to address our culture of crime pretty soon.
