After the terrorist bombing attack that occurred in USA in September 11, 2001, the US government set up special security agencies that are responsible for handling security activities in US airports. September 11 security fee is part of the money that is used to fund these agencies.
I think that eventhough, Federal Government has too much power and is it wanted it could change the life of their citizens from one day to another, it also gives to the states to act with freedom and decide how to live in society in their terrotories with their own laws. This a positive feature of the Federal Government, allowing the states to act with certain freedom and ruling their territories by them selves.
In my opinion there are not good or bad powers, but there good or bad people so it does not depend on the powers, it dependes on the people that has them and how they use it. For example the Federal Government gives the states to choose if the marijuana is legal or not in their territories and nowadays sevral states legalized it and others do not. In this case for example it dependes on the control that the State Government does over this matter and that pople respect the rules of how to use it and consume it. This matter is really important and affects the economy of the United States, but if the Federal and the State Government cooperate to control and give this industry a conscious and responsible use, this is a good choice that both authorities are making.
