more rights than the average person.

This is established in the 9th and 10th Amendments to the U.S. Constitution, which were created to ensure that people's rights were not limited to those only specifically mentioned in the U.S. and to prevent the government's power from expanding. They state the following:

Tenth Amendment: The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
