The relationships among the various values and norms jostling for position here are complex. Notice that if our foremost concern were to establish and sustain a society in which careers open to talents along with the substantive equality component of FEO is satisfied and there is also a high level of social mobility, one strategy would be to ban assortative mating or enact policies that discourage it. “Assortative mating” simply refers to people choosing to cohabit with those who are like themselves along some favored dimensions of similarity. These dimensions might include race, religion, national origin, level of education, inherited wealth, physical attractiveness, charm, or marketable talent. The assortative mating that reduces social mobility involves sorting by factors that give rise to unequal income, wealth, and status.  Although many might dislike the outcomes of such assortative mating, few would countenance restrictions on individual liberty to date and marry in whatever way people happen to come together by mutual consent. However, social policies could alter people's incentives without directly restricting their liberty to date and mate as they choose. For example, highly progressive taxation rates on income and wealth would reduce the financial gains that two well-off persons could achieve by getting married.
