Why does the supreme court ignore the constution?

"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."

As you can see, it's all about the people, not Congress, not corporations, not the Supreme Court, not even the President -- THE PEOPLE
