Kon,  My point is that federal money does and always has supported Alaska. The road system areas of Alaska take up the majority of the state budget. Granted, these areas has the majority of the state's population. 

Bush Alaska isn't the problem. In fact, Bush Alaska is where all those resources tend to be concentrated.  Costs will remain high in Bush Alaska until roads and rails connect it to the primary road system.
Isn't getting any cheaper to wait on doing it.
