The Role of Government? It’s right there in the Preamble to our plan of government, our Constitution!
We the People of the United States, in Order to:
1.) Form a more perfect Union
2.) Establish Justice
3.) Insure domestic Tranquility
4.) Provide for the common defense
5.) Promote the general Welfare
6.) Secure the Blessings of Liberty to ourselves and our Posterity . . .
Do ordain and establish this Constitution for the United States of America.
Of course, the Democrats reinterpret “promote the general welfare” as “promote the welfare state”.
