Why is Rush so Cut-throat on the Sororities' End at Big Greek Schools?

[twinstars]

I think it can be cut-throat among the top sororities, competing for certain rushees, because even though there are plenty of girls rushing, there is always that top 20% of the pool (or so) that any of the best houses would love to have. If you do succeed in getting those rushees, it's a big ego boost. It means your house beat out the competition (other very good houses). Guys talk about it.... "oh, did you hear theta (or whoever) got so-and-so? Her dad's the president of .... whatever"

It's so competitive because the top tier of sororities are all going after the same set of rushees. There aren't enough of those "cream of the crop" rushees to go around... someone's got to get them, and it might as well be your house.
