I just want to make a quick recommendation for some fun reading. The book Pledged: The Secret Life of Sororities” by Alexandra Robbins is a great look at sorority life. While not being overly harsh it paints a picture of the way that sororities exert control and influence over people. I have seen the good and bad sides to greek life many times during my career at Lehigh and this book captures all of it very well. The philanthropy can be good when they are not simply buying their way out of it. The brainwashing is an unfortunate side effect of group think but there is little that can be done about it. You take girls who are a semester out of high school and wonder why the emulate high school like behavior in the organization that they created. That being said I will let you read the book and decide but it is something that can be enjoyed by all non greeks out there.
