There are also benefits to the difference in social mix at the CSU’s – so the affect is not necessarily negative. The average age of the student body tends to be older, with more non-traditional students, including more students who enter at an older age, such as students who opted to do a stint in the military before college. That leads to a more mature student body overall - less of a party school atmosphere. So a less school-centric social atmosphere – between the working students, the older students, and the commuter students who still live at home- it is less likely that the students do their socializing on campus. But for any parent whose kid messed up at college because their dorm life was one continual party-- that can be an advantage. And the CSU campuses do have students who get very involved in campus organizations and student government - plenty of opportunities for that.
The CSU’s do have problems, primarily due to funding levels – but when I attended my son’s graduation, I saw a whole lot of proud students graduating in a stadium. (On of those interminably long ceremonies which cause parents to wish their kids had majored in Anthropology.) It’s just a different mix.
