Some interesting dynamics are going to come into play in a few years, and beyond. As travel becomes less and less affordable with the price of fossil fuels climbing as supply starts to decrease, the American workforce will make increasing efforts to live near their places of employment. In large metro areas, where most of the population lives and works, distance from the office seems to be a determinant in housing location for only a small percent of the population. Most people have certain neighborhoods they like for various reasons, but home affordability is obviously key. A lot of people, perhaps most, consider where they live to be more permanent than where they work, so rather than trying to live as close to work as possible, they just focus on affordable neighborhoods within the distance they're willing to commute to work. So what will happen when the lower and lower-middle class can't afford to pay for gas to get to work? Buses can't go everywhere; they can pick people up at Park and Rides, but what if the final destination isn't in a major urban location (i.e. not in a spot served by mass transit)?
