“while the impact of social class, ethnicity, and religious socialization on marital choice has been diminishing, educational homogamy has been increasing.35 In general, the college-educated population (which encompasses the upper-middle class as defined in the present study) continues to show a high degree of similarity in its cultural practices and attitudes over a wide range of areas.36 The fact that a college degree remains the best predictor of high occupational status suggests that the boundaries that this population builds between itself and others are particularly significant.37 These boundaries are likely to be more permanent, less crossable, and less resisted than the boundaries that exist between ethnic groups, for instance. They are also more likely to survive across contexts, i.e., to be carried over from the community to the workplace, and vice versa. We see again, therefore, the importance of studying in a systematic fashion the boundaries produced by college-educated people.”
