The existence of California -- and San Francisco, in particular -- makes discussions like this one difficult, because yes, sure, San Francisco is too weird to exist and is therefore basically irrelevant in national policy discussions.
I live in Rhode Island. East Coast. An hour from Boston. Expensive real estate, high-COL (top 10 or 15, depending on which numbers you trust), etc, etc -- and yet, we are just absolutely nothing at all like California, which is its own very weird outlier that has nothing to do with the experiences of the almost 300 million Americans who aren't Californians.
