Answer:
D. promote capitalism
Explanation:
The government of the United States has many purposes, as does any government around the world, and they are written in the Preamble of the US Constitution. Establishing justice is one of those things, as a just system is a must for any democratic society, and it is also crucial for not allowing corruption to spread and certain individuals to gain way to much power over everyone else. Providing common defense and ensuring domestic tranquility are also things that are vital, as it ensures the safety in the country, be it from foreign offensive or from domestic destructive structures. The promotion of capitalism though is not something that can be found in the Preamble of the US Constitution. While it is not something that is a must for the government of the United States, in practice it has actually been acting as if it is, and for more than seven decades now the US government has been promoting capitalism around the world.
