Social Hierarchy Etiquette in United States of America

Social hierarchy in the United States is relatively informal, so people usually address each other by first name, expect direct eye contact, and judge status more by job title, expertise, or confidence than by age or family background. In more formal settings such as business, government, or elite schools, rank still matters and people may use titles and credentials, but everyday interactions tend to emphasize equality and friendliness rather than deference.
