Yes. A lot of donations to schools are earmarked for specific things like libraries and sports complexes bearing the donor’s name. The university is then forced to hire all kinds of staff to run and maintain these buildings, lest they ruin their reputation by allowing the fancy buildings to fall into disrepair.
Donations that are earmarked to help students are in the form of scholarships and bursaries. To be honest, there aren’t nearly enough of those to go around.
