Not only that many of the founders outright said that it should be completely replaced one a generation, Thomas Jefferson famously said

“I set out on this ground, which I suppose to be self-evident, ‘that the earth belongs in usufruct to the living’; that the dead have neither powers nor rights over it… On similar ground it may be proved that no society can make a perpetual constitution, or even a perpetual law… Every constitution, then, and every law, naturally expires at the end of 19 years. If it be enforced longer, it is an act of force and not of right.”
