As our economy expands, freight will increase tenfold and more. Texas will have high-speed rail because its size and cities demand it. Southwest Airlines only delayed it, at great cost to the taxpayers. Oklahoma does not have the size of Texas, nor the cities Texas has, so Oklahoma must be the link to the rest of the country. Oklahoma is small, so Oklahoma will be the crossroads or the by-road.
Bureaucracies always expand.
It takes great effort to constrain them. Government bureaucracy has no profit motive to force it to downsize, so there will always be a continual need for more tax. Perhaps it is time to spin off more government to competition. Unless government becomes more manageable, additional taxes will always have to be found. This will be a challenge.
