Bill Clinton, as president of the United States of America, is entitled to the exact same human rights as a drug addict on the streets of Hartford and vice versa. We are all human. The idea of a person's worth being based on their humanity empowers the individual. The empowerment of the individual leads to assertive exercise. Individuals are able to stand up for themselves, to voice their needs, to demand justice, and to receive the help of others.
Assertive exercise is, in a sense, the essence of human rights.
However, it is not their primary goal. Human rights aim to be self-liquidating. They allow for assertive exercise but strive to create a society in which rights are not necessary. All humans are entitled to their rights but ideally, should never have to demand the incitement of them. And in some cases, this ideal is somewhat of a reality.
