Amazing video of brand new suburban homes being razed by bulldozer. Apparently, Guaranty Bank of Austin took over the homes in foreclosure - four in a suburban Texas development and another 12 in one suburb in California - and is knocking them down ostensibly to promote a "safe environment" for neighbors, and more likely because it is cheaper to destroy them them to keep them on their books.

This may be just the tip of the iceberg. Once desired, suburban and ex-urban communities with cul-de-sacs, McMansions, and long commutes could be on their way to becoming the blighted and abandoned communities of tomorrow, accelerating the process Chris Leinberger documented in his eye-opening Atlantic essay of March 2008.

Not to mention that this entire development cycle is a giant waste of resources and a potential drag on long-run economic competitiveness and prosperity.
