From the Post Sustainability Institute:
Economic collapse creates a chain of events, but on a micro level (county, city) there is a marked reduction in revenue for maintenance of services. Loss of services to outlying areas means, for example, roads not being maintained to rural and suburban areas. Roads not being maintained to those areas, schools not being supported in those areas, law enforcement/fire/social services not being supported in those areas means a gradual movement into the denser city centers. Add to that the increased cost of gasoline (manipulated), and the higher cost of energy (manipulated) to heat and cool statistically larger homes, and you have more pressure to leave rural and suburban areas. Reduction of energy usage is key. Smart Growth/New Urbanism in Redevelopment Areas is the supposed answer: smaller units, attached condos, little or no parking, few private cars. More eyes on the street. Redevelopment projects are the implementation arm of the UN plan, and include rezoning of huge sections of your cities to Smart Growth zones. This physical manifestation of UN Agenda 21 is social engineering paid for with your property tax dollars. These areas then have their property taxes diverted away from your services and into the pockets of a few developers and bond brokers for 30-45 years. Result? Bankrupt cities and counties.
