I think the way rush has been pictured in this thread does make it seem superficial. Speaking for my chapter, who participates in formal rush, we don't let just anyone in. EVERY girl that comes on bid day has at least one recomendation from an alumna, who has to actually know the potential member. The majority of the girls have shown previous interest in our organization and are hometown friends, roomates, college friends with a member. I think loyalty is directly tied to how much time and commitment you put into membership recruitment. We may cut a lot of girls but the girls we get are the ones we really want. Less girls during rush parties allows members to have deeper conversations and get to know the girls which is better than having tons of girls coming back every round. When new members are initiated and shown how rush works for our chapter they often think "How in the world did I get in!" and realize its because the members truly wanted them and took the extra time and effort to get to know them. We also have an extensive pledge education program. Your not going to sit in a seminar for hours a week. Take test. Recite creeds and other ritual if you dont realy want it. People do de-pledge. But the ones that stay that realize that the respect, devotion, and sincere caring of our house. All this comes together to makes people loyal.
