“Growing up, I was like most Americans in my reverence for the Constitution. … Until I took Constitutional Law at Harvard Law School. The experience was completely disillusioning, but not because of the professor, Laurence Tribe, who was an engaging and open-minded teacher. No, what disillusioned me was reading the opinions of the U.S. Supreme Court. Throughout the semester, as we covered one constitutional clause after another, passages that sounded great to me were drained by the Court of their obviously power-constraining meanings. First was the Necessary and Proper Clause in McCulloch v. Maryland (1819), then the Commerce Clause (a bit) in Gibbons v. Ogden (1824), then the Privileges or Immunities Clause of the Fourteenth Amendment in The Slaughter-House Cases (1873), then the Commerce Clause (this time in earnest) in Wickard v. Filburn (1942), and the Ninth Amendment in United Public Workers v. Mitchell (1947).”
