The American dream: go to college, get a job, move to a nice house in the suburbs. Like this.
Here is a picture of a Phoenix suburb. Houses sprawl endlessly into the desert taking up more and more space and moving further from the urban core. An even more dramatic example is this picture of suburban Los Angeles.
When will it stop? It has become extremely challenging to actually move between the suburbs and the city center.
Suburbs are extremely inefficient and cannot continue to spread outwards from city centers. In Los Angeles, it takes 30 minutes without traffic to reach downtown from the outer edge of the city. Considering suburbs that extend outside of the city limits, commuters can often drive upwards of an hour to work each way. Not only is it annoying to spend two or more hours commuting a day, it is unnecessary.
It seems that Americans are finally feeling fed up with the suburbs and beginning to move back to city centers. As cities grow from the center, they can offer more and better services to their residents. Living in a community like the ones pictured in these photos is becoming an unattractive venture. I hope that the trend of downtown urbanization continues over time.
