I completely agree with your point, but that's not a problem of renters, per se.

If the city of San Francisco (where my wife and I live) made a committed effort to build a stable stock of rental property that allowed families of 3-5 to rent for less than $3k a month, I guarantee you'd see more families sticking around instead of fleeing to points north or east. Instead, you get mostly young, single (your "bowling alone" category, less likely to show up at those city council meetings) splitting 3 bedrooms four ways and paying $4k for the privilege of all sharing one kitchen and one bathroom.

I'm optimistic that all of the new housing being put up in SOMA will help alleviate this but there needs to be some complementary regulatory structure to help keep those community types (which are often what the young singles become in 5-10 years) around. Otherwise, SF is quickly on a path towards being a place where only the rich, the young, the single, and the poor (via subsidized housing) can afford to live. The middle gets squeezed.
