The Preamble is quite concise. It points to the nature of how the Constitutional Convention intended the mission of the government and society to organize. Our prosperity is focused on what seems to be fundamental to political thoughts on a nation-state.

We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
