We need to rethink how we live in America. Build communities, not just groups of houses for as far as the eye can see. Many of the problems we constantly talk about in this country have so much to do with the way we live. Health care costs wouldn't rise so much if we walked where we needed to go instead of sat in a car. Personal debt wouldn't be so unmanageable if we weren't spending so much money on houses we don't need on plots of land too big to manage. Education would be more effective if parents could spend the hour they spend commuting home from work actually interacting with their parents. The war on terrorism is being funded by corrupt oil producing nations, that we could cripple but simply cutting our oil consumption. And public spaces would promote actual human interaction.
New Urbanism offers a step towards achieving all of these goals.
