U.S. Financial Contributions to the United Nations: Is It Fair for America?
Michael J. Sandel in his book Justice: What's the Right Thing to Do? has tried to report morality by saying "The way things are does not determine the way they ought to be." Although this is a standard notion, let me explain why this may not apply to the question.
We must first understand the necessity of centralized power that the US governs. It acts as a parent body to the rest of the world. The wars are implicitly not for peace but for governance, because on paraphrasing Foucalt, we understand that it is necessary to keep the constant shift of power between the oppressor and the oppressed. It is a responsibility as much as a liability of the governing body to provide the strongest support to the governed states. Here, the world is considered as the governed state, and the support in a post modern world, comes as financial contributions.
According to common statistics on Wikipedia, 22 percent of the entire UN budget in 2017 was contributed by the United States in comparison its next largest contributor, Japan, which contributed almost 10 percent. This is and agreed on status rather than fair.
