All growing things have different needs at different ages. Newborn mammals need milk. Later in life milk can become toxic if ingested at all.

During the generation following the Revolutionary War the United States needed the jurisprudence of the Marshall Supreme Court in order to grow effectively, in order for commerce to thrive. Decisions that may have served a great purpose for one hundred fifty years may begin to have an opposite effect thereafter. How much of our foundational legal precedent is now doing more harm than good?
