At the time, room & board in a dorm was $2,000 a year, so joining a frat was another $2,000 a year on top of that.

The guy I cited above we were friends with when he was between frats. We didn't really see him after he rejoined. Most of the frat members lived together, off campus, in their respective houses, so the rest of us didn't see them unless we went to a party at a house. I'm sure there were some people with friends not in frats, but the setup made it a pretty closed-off world. I'd pretty much see frat members in class and that was about it. Most of the frat houses were all clustered together in one corner off campus.
