In my mind, 'states' have become largely obsolete entities with the advent of instant communication and rapid transportation.
What function, if any, do state governments serve in this day and age? Most of the time, the answer seems to be "little if any."
We have the Department of Transportation to maintain interstate highway systems. We have the Dept. of Education to establish a coherent curriculum and reasonable standards for the nation's public schools. Same deal with the Departments of Defense, Justice, Interior, Homeland Security, etc.
Aside from being interesting historical curiosities, where do states fit into the big picture of 21st century American life? Have they not become little more than arbitrary lines drawn on a map? Or an inspiration to mint new quarters?
This should spark some interesting debate.
