That is so sad to hear about the USC chapter of Alpha Gam. USC's greek system seems very stratified, and not at all Panhellenic. I worked at an upscale women's clothing store in Pasadena in the nineties. Many of our customers were USC grads, and they were sorority alums. There was much talk of "good" and "bad" chapters at USC. (Most of these women did not work, and shopped as a hobby.)
