The document you are referring to, is the Declaration of Independence, not the Constitution.
Also, if you read the Declaration of Independence, you would see the sentiments expressed are about protection of individuals rights, rather than redefining them as something an external party can manipulate at the expense of said individual.
I don't think it was written very well though as it presumes that one form of government is necessarily replaced by another, and that by doing so, individuals rights will be protected. That of course hasn't happened.
