To whom are the responsibilities owned to in the Preamble?

What are the related costs and benefits?

I don't understand your question.

Here's the Preamble to the U.S. Constitution.

can i ask a different question instead

Sure.

What are the sources of the responsibilities?

Your question still doesn't make sense. Do you mean who is responsible for carrying out the different ideas in the preamble?

And here's an earlier post today that may help:

I don't find anything in the Preamble that addresses the "sources of the responsibilities."

We the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, 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.

Other than "We the people" -- I don't either. The Constitution itself sets out these different responsibilities, but the Constitution comes AFTER the Preamble.

That must be it, Writeacher. We the people are the sources of the responsibilities.

That's the only thing that made sense to me when the question was asked earlier today!

Even though they were separated over time by over a decade, I have always seen a direct thread between the Declaration and the Preamble ... emphasis on the will of the people. It's echoed again in Lincoln's speech at Gettysburg.
