Plus and this is strictly me speaking for me. I don’t want San Diego to grow. People leaving is not a bad thing to me. I may not be able to stop SD from growing, but growth is not an endless mantra. Its time at least for now seems over.
On a higher pardigmatic level, there isn’t anything the city/county could do. The forces that shaped this bubble are global, and we are mostly powerless at this point to do anything but take a front seat and watch.
