Is the US Constitution still fit for purpose?

Current discussions question if the US Constitution remains fit for purpose, suggesting a potential need for updates during this anniversary year. Specifically, the 14th Amendment, ratified in 1868 following the repudiation of the Dred Scott decision, provides clear guidance on birthright citizenship. It explicitly declares that all persons born or naturalized in the United States, and subject to its jurisdiction, are citizens. This legal framework remains a central point of constitutional interpretation today.
