Big companies and nepotistic fellows know which politicians to bribe for tax cuts that nullify this.

My state is unlikely to do this as they basically give-away electricity ( vs costs elsewhere in North America ) to lure Aluminium factories here.

I'm sure the next time ''Liberals'' or other leftists win, they will vote something like California did, but will exempt companies from it, for the same reason ( companies hire former politicians and illegally fund political parties ).
