I'm talking about quality-of-life, not absolute carrying capacity. I like having pristine natural areas, open spaces, navigable freeways, a labor pool that isn't absolutely desperate for work, etc--not to mention basic goods that don't cost an arm and a leg because of intense demand and competition. Yeah, technically we COULD support a lot more people, but who really would want to live like people do in India or Hong Kong? California is way too crowded as it is, at least.
