how can this be so? i agree it sucks that {insert middle class profession} can't afford a 3br in the bay area or NYC, but how can that be the root cause of inequality across an entire nation? there are tons of affordable 3br houses around where i live (mid-size coastal city).
i see that it is a bad thing for service workers the wealthiest cities to be pushed ever further from their place of work, but this seems like a more local problem.
