suburbs just don't scale. If the population of the USA keeps increasing, this country has to move forward into more urbanization, more density, and higher buildings and mass transit. When I moved to California, I was surprised that its architecture had more in common with the Midwest than with the more urban east coast. Appart from SF, you have to have a car to go anywhere. In the east coast, from Boston, to D.C. you can get along fine with urban transport + zip car. But I realized, most of the cities in the east coast were created centuries ago, and were made for people, and not cars, and tend to have higher densities (even comparing suburbs to suburbs). Unfortunately, most Cities in CA, were made for cars. (with SF being the exception). There will be natural forces that will make cities to increase their density. LA is already a big giant parking lot, how much further can it expand? All the bay area highways (all 5 lanes ), are already clogged all the time. What will happen when there are 20% more cars in the street just two decades from now? People either have to endure long hour + commutes, or live close to their working places, or choose their work and place to live according to public transport accessibility. Necessity will shape this nation. It wont happen overnight, but in few decades things will be different.
