I can help you with that:
First of all it is not even constitutional to impose broad based taxes without eliminating the Dividend. The Dividend is not a "legitimate government purpose" and any form of individual taxation would invalidate it.
Secondly, there is no disputing that the Permanent Fund Earnings will be funding our State Government annually to the tune of around $2.0 billion/year in one form or another.
State Budget Cuts,  and new taxes will suck more money from our economy. The CBR is our lifeline to slowly reduce the deficit and impose new revenue measures where needed. Any supposed harm to the poorest among us will be compensated with the benefits of Medicaid Expansion and reinforcing our existing social service programs. Erickson's main point is that we are going to suffer an economic contraction - the strongest will survive and the weakest will perish but it doesn't have to be a train wreck.
