Class vs Status
Class is the category you were born into. Status is the position you currently hold.
The two are often discussed as if they were the same thing, but they describe different layers of the social system. Class is structural — slow-moving, partially inherited, woven into family, education, geography, and the long accumulation of advantage or disadvantage across generations. Status is positional — faster-moving, more individually earned, shifting with circumstance and demonstration. A person can have high class and low status. A person can have high status and low class. The combinations produce some of the most revealing patterns in modern social life.
In some societies, class and status are nearly identical — the class you were born into determines the status you can hold. In modern societies, the link is looser. Class still shapes status powerfully, but status can be acquired, lost, and rearranged within a single lifetime in ways that class cannot. Understanding which is which clarifies what a person is actually working with — and what they are not.
