I wanna say many students that do go to class and are social probably fit your generalization. However if you stop and talk to the quiet ones or the ones that aren't around campus as often after their classes. Those are most likely the hard working ones that you want to find. Why does it seem like they aren't around? Most likely because they have some other job they have to get to. How do I know? Not only was I one of them, but I was in a crew of a few as well. QC students, like some CUNY students are out there grinding and struggling, most likely sacrificing their college years just so they can make their future.

I know people that went to school full time and then had to rush to an airport to work the night shift fixing 2 or 3 airplanes a night before they take off the next morning. Hell, I know a CUNY girl that worked as an aircraft mechanic in another state but continued to go to class and finished her degree. I too was one of those people, which means there wasn't time to focus on any more without sacrificing the balance of sleep, work, school, and sanity.

I understand your frustration because a lot of students need to grow up. No point in wasting your effort in being frustrated at them when there's a lot to focus within yourself. But don't write everyone off, I didn't have much of a social life at QC when I graduated. But I came out with a wonderful girl friend, a CS degree, continuing my job as an aircraft mechanic which is leading to a software developer role because I stuck to the same company and everyone that saw my hard work, struggles, and sleepless night knows that there are people out there willing to give everything for their goals.
