The Constitution was expected - as described in the document itself - to be reviewed and revised and updated every 20 years or so. The last one proposed and ratified was in 1971, 55 years ago, the 26th, around lowering the voting age. (Yes, there is a 27th, but that was proposed in 1789 and just took two centuries to be ratified - guess what it was about? Prohibiting Congress from changing their own pay in the current election cycle...).
