Playing devils advocate here. If it was so perfect, why did it need amendments? At what point do we know we are truly done adding? Is there more room left?
Discussion
The Framers of the Constitution provided for the addition of amendments. There is room to add amendments. An amendment may be proposed by a two-thirds vote of both Houses of Congress, or, if two-thirds of the States request one, by a convention called for that purpose. The amendment must then be ratified by three-fourths of the State legislatures, or three-fourths of conventions called in each State for ratification.
