Wow, I'm amazed this thread is going this long.
I agree with much of what's been said here (having said some of it myself

), but it is not so simple as picking up and moving to the city so that you're closer to your job. What happens if (when) your job outsources you and you have to find another job? Every time you have to move it can be really expensive, regardless of whether it's across town or across the country. If everyone was going to maintain a sense of mobility to the point that you could cheaply get up and move at any time, we'd be in the 2nd Great Depression already. Remember, moving at a whim was what you did then, because you followed the jobs. You certainly couldn't "settle down" if the company was only hiring for 2 weeks.
This is what many people are faced with today. Sure, some dopes think it's great to live in neverneverland and commute. Most people live, or lived, within reasonable distance from their job at some point. When they had to change jobs, the fact that everything is spread everywhere meant that their new job might be spread far away from their current residence.
I am a prime example. I have worked at jobs, in my life, with the following commutes:
50 feet (right next door)
.4 miles (10 minute walk)
<5 miles (10 minute drive)
<10 miles (15 minute drive)
24 miles (35 minute drive)
35 miles (over 1 hour, 2 in bad traffic)
50 miles (50 minute drive)
There have been others, but those are representative. Sometimes I have been fortunate enough to not need a car to get to work. More commonly, I've driven >10 miles because that's where the job is. Considering that I'm not far from paying off my mortgage, can I really afford to sell the house and move every time I switch jobs?
The fact that everything is spread out is also the reason that public transportation has not worked well in the US in the last 25 years. Without a central hub, doing anything but driving is generally impossible. People also shouldn't forget that suburbs are not the invention of the automobile. Suburbs in the US started gaining serious popularity in the mid 1800's, and were accessed by horse & buggy, trolley car and trams before the automobile took over.
After fueling up their cars, Twyman says they bowed their heads and asked God for cheaper gas.There was no immediate answer, but he says other motorists joined in and the service station owner didn't run them off.
