Make your neighborhood your family

Here’s an article by the same publication that gave us the one on Bhutan.  A part of their happiness series I guess.  Be sure to read both pages!  Anyway, what do you think of the diagnosis of the problem (families no longer work because of a lack of community support) and its solution (creating a community in a purposeful and perhaps somewhat artificial fashion)?  Could this work in Slovakia or does it depend on culture and/or income level?   Is it realistic to try to do something like this in the modern age of mobility and virtual reality?  What has your experience of neighborhood (tightly knit or otherwise) and neighbors been like?
