Universities themselves are chasing university rankings, which count publications and impact factors. Does a 17 year old kid or their parents know how to judge a universities quality? No, they use prestige (rankings).

Nobody has time to read everyone's papers, or evaluate someone's knowledge thoroughly, so we fall back on things like degrees, impact factors or university prestige.

Once you realise academia is all about signalling - being able to quickly judge people - everything makes sense.
