By quality of education no. As a method of pre-filtering candidates sure it’s pretty obviously when someone comes from an extremely privileged background.

Also there isn’t really much difference between Cornell, brown, or pen graduates from Any of the decent state schools. Except they are full of themselves more.

Honestly the graduates from 2nd tier state schools seem to have gotten the best education but they had adverse selection coming in because their more competitive peers went to higher ranked/named schools.
