Robert began his Own financial services firm some 40 years ago because the partners at the firm where he originally worked declined to recommend him for membership at an elite private country club. New applicants for club membership must be recommended by existing members, and it is expected that they would come exclusively from the highest social class group. One of the
partners who was friendly with Robert told him in confidence, "We love the work you do for the company, but the feeling among the partners is that you're just not one of us." Robert resigned that day and opened his firm the very next week. He did well, though it took 30 years to grow his firm into something reputable. However, his upper-middle class pride never truly recovered from the injury until all these years later, when his son, a renowned surgeon, was recommended for membership in the club by the partner that would not consider him. What social class is Robert's
son most likely to be in?
