You seem a little bitter towards college grads in general but especially toward fraternity men.
Don't let your own unhappiness cloud your judgement.
No one in my family ever graduated from college. I determined to change that starting with my family. Our three sons are on their way. The oldest enters law school in about 18 months. While none are in fraternities, they understand if they want to join they pay their own way. We discourage being a 'joiner' to anything, save a good church.
