You aren't really sure how the system works are you? Unconstitutional legislation is passed all the time. It doesn't mean that it will hold up in the long run. If this trend catches on expect a pretty major series of court cases in the future. The results of which will actually definitely answer this question.
Most likely I know more than you since I actually hold a Master's degree and vote every year for my local representatives. You remind me of the guys who oppose healthcare reform and believe it will not be the law. It is the law, it was passed in congress and some parts of the reform are already active. The same will apply with this tax reform in California. Suck it up.
