You can't possibly be that stupid? It's right there in the preamble of the constitution:
Its first three words – “We The People” – affirm that the government of the United States exists to serve its citizens.
IN addition, the Declaration of Independence stated "That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."
