If people keep moving away, then eventually, there will be no where to go after all the "good places" are filled up, then eventually infected by human evil. Humans are humans. Its sad, however, I believe that today's world is fast paced, stringent and unforgiving. This is a breeding ground for disenchanted youth and evil to begin. Evil wins when good men do nothing.
That has not proven to be the case in Houston, Texas at all. The inner city neighborhoods where Suburban folks dared not tread have changed. The property values went up and people with money started moving back in. Those bad neighborhoods no longer supported poor folks and they moved out to the suburbs where I used to live.
The suburb of my youth (70's) is gone baby, gone. Drive the main drag and if you don't speak spanish, you don't know what each business is. White flight is right... that is exactly what has happened. They have moved to further out suburbs where commute times are not measured in minutes but "an hour and......". Where the center of your Universe moves outside the city.
11 years ago my wife and I were driving around looking at Christmas lights in our 'inner suburb'. There were 5 or 6 youths on a street corner at a light. When I stopped, one of them walked out and spit on my car. As I unbuckled my seat belt, they all started talking... "Come on ******, get out of your car you chicken **** *****...." There was no doubt in my mind their entire idea was confrontation and I was falling for it.
Luckily my wife grabbed my sleeve and screamed at me... I mean it scared me... GET BACK IN THE CAR AND DRIVE!!! Luckily I did. That was not the first weird thing that had happened to us in our first house. But it was the last. We moved less than a year later. That neighborhood went downhill so fast, it turned into one of those that most people would not drive into for any reason.
Within that 11 years, it has now come full circle... people with money are buying up these smallish homes on big lots (my back yard was about 1/3 acre) that were built in the 50's and rebuilding them into McMansions. Could I have stayed and made money? You bet. Do I regret it? Not for one moment. We were very scientific about where to move... breaking down the entire city into quadrants with no maximium distance limitation. As we ruled areas out, by default we ruled other areas as more likely until we found the place we wanted to live.
She doesn't live here any more, but I do!
And I absolutely LOVE IT. My problems with teenagers are the usual loud music, driving too fast and very rarely one coming home late at night drunk and loud. I made money on the sale of my first house. I didn't have to spend a fortune turning it into a fortress. I stopped having to repair vandalism. I don't feel the need to grab a 1911 just to check the mailbox. How much is your peace of mind worth to you?
