Isn't that what has effectively happened given the massive cost of living increases in CA? 100-150k income only affords a middle class lifestyle in many areas, yet the tax brackets did not necessarily keep up with the times. If costs of living had instead gone down, you can bet that the state would have at least tried to make adjustments in their favor if they could get away with it (likely so given the long history of tax increases).
