Higher education is instrumental in generating economic and social mobility, and networking within higher education communities is essential to that process. Student-alumni networks promote the transmission of social capital across generational and class lines and are often just as important (if not more so) to graduates' success as their degree itself.
Intergenerational connections produce the most worthwhile alumni relationships because they let older alumni offer advice and opportunities to their younger, less established counterparts. Without intergenerational networks, resources can only travel laterally among alumni in the same cohort, and the potential of alumni communities is squandered.
