Good point.
Although even if oil company profit per gallon were proportional to price (it isn't), for them to clear as much profit as taxes take in California, gas prices would have to hit something like 20 bucks a gallon.
Like the cigarette tax, it's another case of unintended consequences (at best). Force high-mileage cars on us, then wail that gasoline consumption is going down. It has been seriously proposed to track mileage on cars and tax that.
A grotesquely bloated State, financed by taxes, demands a society of ferocious production and great wealth to support it. I doubt that those "progressives" trying to make our country "small and beautiful" have thought it out that far.
