New group classification????

we watched a TV show called freaks and geeks. and those apparently were 2 pretty recognisable groups in high school life. but what about today. could we really classify ppl into groups such as these. i feel that in todays society people don't have one set group they move among several. i also believe there is no hierarchy or "food chain" to the groups that do exist. some of the groups may attempt to establish domonince but no group ever seemes to. all this is true, i believe among the kids. i no that the adults will give special privliges to certain groups. one group would most definetly be football players. there have been several times where a security guard would tell a student that they couldnt open a locker room or that they couldnt bring food down the hall and when the football player would ask for the locker room to be opend there was no hesitation and they will usually let us bring food. but i only no this from being a football player other wise i could not tell who who or what group has any power or if there are ever such deffined groups as there used to be in high schools
