Why are recs absolutely necessary at some schools, while not expected at others?

My biggest problem with the "recs required" systems is it is patently unfair to anyone who grew up outside the south, and since students are traveling all across the US (and worldwide) to go to school, this seems like a step to limit the chances or increase the stress factor for the girl who isn't from a large'ish southern city who's mom wasn't a socialite.

My guess is, and for dog's sake don't take this to the bank, there ARE chapters in the deep south where recs are actually NOT required. But would I want it put on record that my sorority doesn't? Hell no. It would have the affect of saying we are less selective. Unless my sorority's MS system has changed dramatically, recs have a role, but I can't imagine that one element being enough on its own to get a girl cut unless she was low on the bubble anyway. And if I'm correct in this thinking (that they don't hold as much weight as we like to say), then I think stopping talking about it so much would be really really helpful. If it were possible to go back to only writing recs for girls who you personally know so that they were an actual leg up, then I'd be all for that. But while we keep saying they are absolutely positively, you not only aren't getting a bid but you might get kicked out of school and probably will never have friends in your whole life required, then girls will continue getting them for every chapter, regardless of how tedious or unhelpful.
