Fair question. I know something that is not the role of the US govt.........trying to micro manage the country or human behavior more precisely, by enacting laws that are more concerned with the "ends" as compared to the "means". The "means" to the end and principle (Constitutionally based) based laws are what we need. We don't need short term non principle centered laws that are more concerned with the "ends", ie: affirmative action. When a large federal government feels it's duty is to regulate every last bit of human behavior, we have lost. Our federal government should manage our international affairs and let our domestic economy take form however it shakes out via capitalism. Sorry I couldn't provide a list, just some rambling.

Just a few off the top of my head. Oh wait... you said what 'IS' the role. My bad.
