The question was "How would incorporating Talkeetna help their problems?" I answered that question by suggesting that, if incorporated, Talkeetna could decide to create a sales tax and use the revenue generated for local purposes. Talkeetna would have local control over both the tax and the use of the funds collected.

A borough-wide sales tax would not necessarily be primarily used to fund infrastructure improvements in Talkeetna. Most likely such a tax would be used to fund infrastructure in Butte and other neglected parts of the borough as well (not that other areas do not have needs as well, but Talkeetna is the focus of discussion here).
