While this is true for all of the thoughtful people posting here on CC, there are students (i have encountered a few over the years) for whom college is (or was) a waste of time and/or money, at least at that time in their life. These would be the students who are just not ready, really don’t want to be there (e.g., only going because Dad made them go), and/or the students who simply fail to avail themselves of the opportunities presented to them – they are just going through the motions, but are not engaged or involved - at all, in any way, shape or form. Most of these students don’t stick around for long, though. Maybe they come back later, when they are ready.
