I've wondered for a while weather housing exclusivity can improve economies in some respects. Do the high housing costs create a strong selection bias to bring in only the most determined to take part in the SV culture? Obviously, lower housing costs would cause a higher absolute density of people. But maybe the presence of people with other unrelated interests would somehow dampen the tech economy, even if the absolute density of tech people remained the same. Let me be clear that I support more residential construction on the peninsula, so I am not saying this as part of a weird socio-political agenda. It's purely out of curiosity.
