This is a link to an article on the death of suburbia in the New York Times. I've long thought it was time. Here's a money quote from it:
In 1946, when the American post war housing boom started, the average house was 1,100 square feet and housed 5 people. Fifty years latter, in 1996 the average house would grow to 2,200 square feet and house 2.6 people and by 2007, fueled by easy credit, the average American home would would become the equivalent of a Hummer, “weighing in” at super-sized 2,400 square feet.Big cars, big houses, big problems. It all kinda goes together.
