establish Justice

“We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, 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.”

What exactly does this mean? I read it and it says to me that we, the citizens of the United States of America are supposed to be joined together in a great cause. First and foremost we are supposed to “establish Justice”; a word that means; blind, fair, equitable, impartial, truthful and reasonable. This justice is not defined or limited. But on these words alone we the citizens have an obligation to ensure that Justice is the law of the land. To me this means that if Congress has to pass a law to ensure that pay is equitable and that people are treated with equality and voting rights are protected for all citizen; then they have a Constitutional obligation to pass such laws. This also means if any law or practice within any state is in opposition to the establishment of Justice then it is unconstitutional. Seems like basic common sense to me.
