That gets a “yes, and…”
It’s silly to pretend that it doesn’t matter. At some colleges, Greek life dominates the social scene. Yes, a kid can still have friends and people to hang out with, but particularly in more isolated areas and non-urban campuses, the social options can be pretty limited.
Everyone on CC assumes that every college kid owns a car, can easily do “off campus stuff” whenever they want, have an unlimited entertainment budget, etc. I think trying to avoid a campus where Greek life dominates is just as valid a criterion as some of the other things folks post on CC as being “Very important”. And being the only kid in your Econ study section who isn’t going on the frat ski trip or the sorority Spring Break beach extravaganza gets old pretty quickly.
