Constitution as base

The founding document for our country is the Constitution of the United States. As a Writer the first line establishes the frame from everything that follows, after.

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.

Assuming you are not a well-educated 18th century gentleman, the above needs some explanation.

• Keep in mind that our "United States" were founded from a "Revolutionary War".
• The underlying notions were a radical departure from the past.
• Western Civilization is based on a foundation from ancient Greek Philosophy.
• Those old Greeks had some good ideas, familiar to well-educated folk from the Enlightment.

Break this down:

• We the People of the United States, in Order to ... promote the general Welfare,
  Pretty much everything else derives from this one central principle.
  1. form a more perfect Union
  2. establish Justice
  3. insure domestic Tranquility
  4. provide for the common defence
  5. and secure the Blessings of Liberty to ourselves and our Posterity
  All the above is meant to ensure that we all "fare well".
• ... do ordain and establish this Constitution for the United States of America.

The key aim, the foundation, is to ensure the common-good for all People of the United States. (Not for just the rich. Not for the aristocracy. Not for the government ahead of the people.)

This was the key idea behind the American Revolution. We should remember.
