I agree, though, that something has to be done to make the information load tractable, such as a single tax rate for the whole state, or else an easily accessible online database.
This totally won't harm business, and is easy to implement.
[To non-residents of our state: California's legislature is pretty disfuntional, and frequently gridlocked over even simple issues. For example, our budget is often months late, tax returns came back as IOUs one year, and the huge chunk of funding appropriated to build prisons due to severe overcrowding that has had us in trouble with the federal government for years hasn't resulted in one new prison.
So don't worry too much over every idea that floats through our Assembly. We're a somewhat pathological case.]
If each increase in expenses were immediately covered by an increase in taxes, it would make the public much more aware of the costs of political promises.
