A role of the people you mean?

Nope

The role of government is to do what the people are unable to do themselves

Or with more authority.

The legitimate object of government, is to do for a community of people, whatever they need to have done, but can not do, at all, or can not, so well do, for themselves in their separate, and individual capacities. In all that the people can individually do as well for themselves, government ought not to interfere. The desirable things which the individuals of a people can not do, or can not well do, for themselves, fall into two classes: those which have relation to wrongs, and those which have not. Each of these branch off into an infinite variety of subdivisions. The first that in relation to wrongs embraces all crimes, misdemeanors, and nonperformance of contracts. The other embraces all which, in its nature, and without wrong, requires combined action, as public roads and highways, public schools, charities, pauperism, orphanage, estates of the deceased, and the machinery of government itself. From this it appears that if all men were just, there still would be some, though not so much, need for government.
Lincoln, Abraham

I would like to add that there are some things which some of the people can do on their own, but that not all the individuals can do.
Things which we believe that is to the benefit all the people. An example is high school drivers ed. Not all people can afford to take a similar drivers ed class on their own, but we are better off if all potential drivers do so.


Once again I am not a fan of using "morals" in this context.
