Most people I know from HS still are drunks, pill poppers, or stoners. Most of them don't have shit and just live at home, sponging off of their parents and then going to the bars at night. These are the upper middle class and upper class people that thought they were going to be ballers and shot callers by the time they were 25.
Most of them date/fuck within the groups, trying to recapture their HS glory days I suppose. Some I've talked to are completely boring and self obsessed. They go insane about status and think that it is my obligation to help them find a job where I work because we're all bros right? I get a lot of them wanting to add me to their Facebook but I usually ignore the requests.
I only know of a couple of people who aren't losers. However, we're all in our mid 20s in an economy that is disproportionately harsh towards people my age. If things improve, within 10 years, maybe they will have made significant strides. As of now, nothing yet. Not that I really care. Not everyone can be rich - the world needs a lot more toilet scrubbers and fry cooks than lawyers.
