If for some reason there was an issue to where air travel was driven up to such a costly price that it was almost mandatory for our economy that companies start delivering things over land, I would not be opposed to the Federal Government going into states in the middle of the country with less built up and upkept high way system and investing a large amount of money to increase it and create a major high way across the middle of the country so that trade could be made easier and for it to help our economy. I would not mind this despite it basically meaning those states would not be needing to spend their own money to make these highways despite the fact it WILL help them a bit by increasing their personal economy. I don't mind the fact that those states are likely, during that time, to be getting far more dollars per citizen than people in California or New York.
Because interstate infastructure is something the government SHOULD give assistance to the states to construct when its needed, because while it may be extra beneficial to those states it is in the interest of the entire country for the action to be done and its within the traditional purposes of the government.
Much the same, disaster relief is something the Federal Government is set up to help provide. On the state side of things, that relief is being done through reducing taxes thus providing money BACK into the hands of the citizens, allowing them to use that money to repair and rebuild and to also invest it into their state economy that helps to also revitalize it. Bobby Jindal can not make the federal government reduce the taxes of Louisianans to help with this recovery, so he requests money from the federal government for something the federal government was set up to help with so that it can also be used to get the people and the economy of his state back on their feet after a NATURAL disaster.
