Thomas Jefferson on “No society can make a perpetual constitution, or even a perpetual law.

Thomas Jefferson argued: “No society can make a perpetual constitution, or even a perpetual law. The earth belongs always to the living generation. Every constitution then, and even every law, naturally expires at the end of 19 years.” Would it be a good idea to reconsider and perhaps re-write the American Constitution every 19 years or so, as Thomas Jefferson suggested? If so, why? If not, why not?
