Why do kinship systems work? Where, if any, would you find a working kinship system within the United States? Give examples for both questions.

This is my answer, am I right?
Most of us are in a kinship system with spouses, children, parents, grandparents, siblings, uncles and aunts. No I cannot find a working kinship within the United State. Basic on the Kinship Classification Systems: Sudanese, Hawaiian, Eskimo, Iroquois Omaha and Crow working kinship system.

You've contradicted yourself.

Do you understand what "kinship" means?
"the study of kinship is the study of what man does with these basic facts of life-mating, gestation, parenthood, socialization, siblingship etc."
Kinship means family. People are kin if they are related to you or married to you or someone in your family.

A typical family has a mother, father, and children. They consider their kinship to include each other plus grandparents, aunts, uncles, and cousins.
