YEP! +1 SF has 11,000 "newcomers" per year that come here by being born here. Some of my most active volunteers are in just the situation you're describing - frustrated by the stress on their families caused by the kids either having to stay at home or move far away.

The councilman from Mountain View who was instrumental in getting the 8000 new homes approved down there was anti-growth his whole life, until a couple years ago when both of his children, both in their 20s, were still living with him. It was a revelation for him. heh.
