Most of other Tier 1 universities where I've known students (Columbia, Mit, Princeton, Harvard, Dartmouth, etc), have much much more proactive support infrastructure to prophylactically protect and suport their students (or at least the undergrads). (whenever a student at one of these schools complains about bureaucracy, I smile at how much more their university cares about/protect students).
Perhaps just at importantly, students at these other schools find it more permissible to openly communicate that they're unhappy to their peer group. At Yale (as of 3-6 years ago), being unhappy was considered socially unacceptable, ie "why are you here then" would be a typical response. Being able to talk about problems amongst your social peer group is very important! (and being unable to is toxic and dangerous)
I've some very very good friends who had terrible mental health issues go unmanaged for years because of Yale's shitty lack of proactive support of students. And thats even ignoring some of the sexual harrassment issues some undergrad women I know there suffered (from their research lab advisors!).
tl;dr, yale is one of the more toxic environments in the ivy league, though to an outsider it looks like one of the warmer communities.
The first step to having a healthy community is making it ok for people to talk about problems and matters.
I speak from the experience of having been a student at yale, a graduate student at another ivy, and having spent A LOT of time visiting friends at many universities. Every school has its faults, but trust least the ones that hide those faults.
