The tax regime in place for the oil companies is one that they campaigned heavily in favor of - while Republicans were in power in the Governor's office and in both houses of the legislature.

The unemployment that Alaska is experiencing has much to do with the price of oil (essentially controlled by OPEC) and the amount of oil flowing through the pipeline.  These factors are a result of market economics and not of politics.
