Final answer:
The preamble to the Constitution discusses promoting the general welfare as one of the purposes of the government, aiming to secure liberty and protect the common good.
Step-by-step explanation:
The preamble to the Constitution discusses promoting the general welfare because it is one of the purposes of the government outlined in the Constitution. The phrase 'promote the general welfare' means that the government is responsible for creating and maintaining conditions that contribute to the well-being and happiness of all citizens. This includes providing services such as Social Security, highways, unemployment insurance, and social welfare programs.
By promoting the general welfare, the government aims to secure liberty and protect the common good. It recognizes that the overall well-being of society is more important than individual interests. However, it is important to note that promoting the general welfare is not the sole purpose of government; it is one of the multiple purposes, along with establishing justice, ensuring domestic tranquility, providing for the common defense, and securing the blessings of liberty.
The inclusion of 'promote the general welfare' in the preamble was not specifically requested by the people of the United States. Instead, it reflects the Founders' vision and intention for the government to prioritize the well-being of the nation as a whole.
