No, Lynn, the establishment of income and estate taxes is proposed in order to do what almost all other state governments do, keep the government running, not sustain the PFD program. Hammond warned that the legislators and executives would spend all that Alaska earned from the oil extraction and sale if it were not protected. He was right. The corporatists tried to do that from day one. 

The PFD program was designed to make the people the actual protectors of the fund and its' long term value for the state. So far that has worked. If the legislators want a smaller dysfunctional government rather than an income tax and cutting off the state subsidies for the most profitable industry in the world, let the people have it and feel the pain. 

But do not mess with the Permanent Fund Dividend program. It is a successful virgin concept and when you allow it to be invaded once, it is no longer inviolable and will simply be raped by avarice and greed.
