Just preference over how and where they live. I'd much, much rather have a far more enjoyable home life in a quieter countryside area even if my weekday time there is significantly less due to the commute. But I know friends that grew up in cities and are bored to death in the countryside. I can't wait to finally rent my own place in a small village when I move away from university in a couple of months.
Yes and no, yes it's preference but urban sprawl is a real problem and every other people pay for the preference of having a large backyard away from the city.
