Societies all over the world have always found a way to distinguish groups of people, typically by placing them in different social classes. Socioeconomic status (SES) is defined by a person’s individual amount of money as well as the connections they have with other people. This can also be heavily influenced by a person’s family. Social mobility allows a person to move to a different class level, or “climb up the social ladder.” Moving up the ladder is often difficult to do for many reasons, including whether or not someone has access to people of different social classes in order to build new networks, and whether someone has equal access to education. Moving down the ladder may also happen if a job is lost, or if key connections are no longer available.
