I hear you, but we are out of space in the Bay Area. Still lots of land in other parts of the country. And quite simply, there's too much money in the Bay Area --with that inequity leading to homelessness in the lowest wage earners-- and too little money circulating in other parts of America (with therefore no low-wage employment opportunities in all the necessary support roles).
