How can the preamble be used to evaluate how the federal government is doing it's job?

The preamble of the U.S. Constitution outlines the fundamental purposes and guiding principles of the government, such as promoting justice, ensuring domestic tranquility, and securing the blessings of liberty. By assessing the government's actions and policies against these stated goals, citizens and lawmakers can evaluate its effectiveness and accountability. For instance, if the government fails to maintain social order or protect individual rights, it may indicate a deviation from its foundational mission. Therefore, the preamble serves as a benchmark for assessing the government's performance in fulfilling its responsibilities to the people.
