Oh and this next part is interesting too;

in Order to form a more perfect Union

The Framers were dissatisfied with the United States under the Articles of Confederation, but they felt that what they had was the best they could have, up to now. They were striving for something better. The Articles of Confederation had been a grand experiment that had worked well up to a point, but now, less than ten years into that experiment, cracks were showing. The new United States, under this new Constitution, would be more perfect. Not perfect, but more perfect.

Greatest document ever? Well hey maybe, but not intended to be ideal in the sense Radar thinks of it. Closer to perfect is all it intended to be, and probably because perfect is unachievable in a world populated by us imperfect humans.
