The funny thing about the whole high school hierarchy is that it's I'm pretty sure it was born out of American stereotypes from the 1950s that kinda got reshuffled.
I was so keenly aware of this in school, and noticed that the splits weren't down extracurricular lines, like sports or clubs, but down grade lines. Seniors and juniors, at least in my experience, were always more regarded as "popular" just because they had more time in the school. And then on top of that, people who came from the same elementary(primary) school and middle school (Jr high) tended to stay together. And thirdly, there was another degree of separation based on academics. We have an AP system here in the states we're kids can take advanced classes to prepare and further them in their higher educational career. So kids taking AP and pre-AP classes also ended up sticking together.
I mean, there was separation based on activity, but was pretty shallow. It's not like there were band geeks and football stars and they never spoke. A lot of of them were friends or were in both extracurricular activities and more. The only thing keeping people on the outside was being in Jr ROTC... yea that's about. Even the theater kids were smart so they had some degree of clout. But this is all my opinion.
Yea they do. I know I did. At least in my high school, people who earned the jackets, wore the jackets. And Texans are sensitive to the cold, so it's great winter wear.
