How status and roles of a person function in the society

In my last post, I talked about Jeremy Lin and "Lin-sanity" has become a subculture in New York City. Jeremy Lin is a professional of basketball so he do work-outs everyday. That is his role.
Every person has their own status and the roles they are in. Status is defined as three main status: ascribed status,  achieved status and master status. An ascribed status is a status that we receive involuntarily, without regarding to our unique talents, skills or accomplishments. In other words, ascribed status is the status that we are born with. For example, our place of birth, parents, first language, ethnic background, etc. An achieved status is a status that we attain through talent, ability, effort or other unique personal characteristics, like being in a high school or college graduate; being rich or poor; having a certain occupation. Master status is the status that when ascribed or achieved status is presumed so important that it overshadows all of the others, dominating our lives and controlling our position in society, it becomes a master status. So master status could be some statuses in ascribed status and some from the achieved status.
For example, my ascribed statuses are Chinese, male, 21 years old and heterosexual. My achieved status graduated from high school, worship team leader in church, vice president of fellowship in church a college student and a basketball player. My master statuses are Chinese, the vice president of fellowship, a basketball player and a college student because they are dominating my life and my circumstances.
I think each individual's master status is the most important because social roles are sets of behaviors that are expected of a person who occupies a certain status, and people are usually behave as their master statuses which dominate their lives.
As the society's basis are built up with people, every single person behaves in the society as of their roles that would operate up a society according to functionalism. Functionalism states that social life consists of several distinct integrated levels that enable the world—and individuals who are within it—to find stability, order, and
meaning. Individuals are integrated into society by socialization, therefore, people are functioning the society because of their roles.
