"Was the U.S. Constitution essentially an economic document?"

The U.S. Constitution was enacted to give our country a basis on which to grow and prosper. It outlined a system of checks and balances between three separate and yet united sects of government; the Legislative Branch, which creates the laws; the Executive Branch, which enforces the laws; and the Judicial Branch, which interprets the laws. These three branches of government coincide with each other, and the rights and laws at the state level. And this is what i believe the constitution was created to outline, this system in its entirety. However, i do believe that along with the outline of the Government, our Fore Fathers weaved an economic system into the articles of the constitution. 

The constitution does a good deal to lay out plans of taxation, and money retrieval to fund its actions. And this taxation is what allowed the Government to exist. Without it there would be no way for the government to achieve any means what so ever. This is supported by Article 8 of section 1. And by reading that article, you can see that within the idea of the legislative side, an economic system almost in its entirety is laid out. Because for anything to work in the system that our Fore Fathers beset, money was needed, and an economic system provided that money. I believe that the the creation of a sustainable government was the primary goal of the U.S. Constitution, but within the Governmental ideas, laid a economic outline for our country.

i felt that the lack of a central government allowed our country to run not as a whole, but as 13 separate countries. With no power to really govern, the colonies lived individually in almost all aspects of the word. They traded with other countries separately, and interacted with 13 separate currencies. They had no desire or need to comply with a central authority, for there was no taxation, or funding, or anything that the congress could take or provide. 

However, i feel that our biggest problem was the fact that each colony wanted to stay separate and were able to do so, because of the central government, or lack there of. All of the colonies had their own ideas, needs, and desires, and not all of those fit what was wanted centrally. Nothing could be decided, or progressed, because the majority had no reason or want to change the current state of affairs at that time. With 13 separate entities, our early country was very naive, and left vulnerable to the surrounding world.

What is an unjust law?

I believe that an unjust law, is one that infringes upon a citizens rights. Any law that undermines a constitutional right, or amendment, is unjust, and ironically unlawful. Many laws exist today, that according to the bill of rights, should not be allowed to be in place, but no reform is ever made.
