But imagine that you have a family, youre established have kids - they have school you have you network of family and friends etc...
I think that the only people who actually ever make this argument are young singles with no kids that think "duh, its so easy to just commute farther!"
The rent difference in say Pittsburg CA to Oakland/SF is NOT that much different -- but the commute costs (time & money) are enormous.
What you may save in rent, you lose in every other aspect of daily life.
To make the argument of "just commute farther" is just too simplistic a view.
It reminds me of Bush saying how industrious and admirable it was for a single mother to have to work three jobs to support herself.
