I'd love to go back to the rural area I grew up in - it's a much better quality of life, stuff is half or one-quarter of the price they are in an urban area, and there's 1/100th of the population. But there's almost literally no employment opportunities. The one major paper mill in the area is folding, and there's going to be an exodus as the hundreds of people people that work there, and the thousands in the supporting industries, get laid off (not to mention further downstream effects, like school teachers or healthcare workers that become redundant as population crashes). There's nothing that's going to fill that void.
- Affordable suburbs usually carry lengthy commutes of unpleasant stop-and-go driving. City dwellers can walk to work or read on a train. Lower commute time is strongly associated with overall happiness. I share your preference for driving over public transit, but not in commuter traffic.
- Children have essentially no independent mobility until age 16, and then only if they have their own cars. In the suburb I grew up in, I'd estimate that mothers spend ~30% of their waking hours driving their children around.
- Though there may be good restaurants, art, theater, museums, etc. in the city, going to such things becomes a special occasion. Life instead centers around malls and multiplexes.
- Many find sleepy streets dull, uninspiring, even suffocating. For some, proximity to centers of human activity is a great deal more valuable than space.
- If you live in a city, you can go out drinking without committing DUI or spending $40 on a taxi.
- Many find the maintenance of a house, tons of unnecessary rooms, a lawn, etc. to be an unbearable and outrageously expensive bore that provides no value. I can think of many things I'd rather do on a weekend than put new siding on my garage, and many things I'd rather do with 5 figures than fix my roof. My home is a place to eat and sleep; I'd much rather invest time and energy and pride into other things.
