Final answer:
The strength of the family constitution largely comes from it being an agreement reached by consensus, which aligns all family members towards a common goal, similar to the legacy of the U.S. Constitution by the Founding Fathers.
Step-by-step explanation:
The strength of the family constitution is often attributed to it being an agreement reached by consensus. A family constitution typically reflects the values, traditions, rules, and goals of a family. It's not just an emotionally binding document, but one that is agreed upon by all family members, thus ensuring that everyone is invested in its success. This consensus-driven document allows for the family's legacy, much like the legacy of the Founding Fathers and the U.S. Constitution, to be upheld across generations. While such family guidelines are not legally binding, they often serve as a strong moral and ethical compass within a family unit, guiding its members and preserving continuity and family unity.
