The thing is Alaska has an unworkable economy, like a neoliberal Venezuela. The state has no reliable source of income - no sales tax, no income tax etc - outside of oil, an industry that itself requires generous benefits and tax credits in lean times to stay afloat. This problem will just get worse and worse if electric cars really start to take a giant chunk out of oil demand.
I think eventually politicians will have to bite the bullet and institute an income or sales tax. A state's economy can't be that oil dependent in the medium to long term.
