58. The one-body problem.

When both a wife and her husband have PhDs, the difficulty of finding two academic jobs in the same place creates “the two-body problem” (see Reason 48). But it takes only one PhD to a complicate a marriage. When one member of a pair makes the long journey through graduate school to a terminal degree, the stresses of that process are shared by both. Moreover, graduate students not only have little income (see Reason 12), but they also tend to be in debt (see Reason 1), so marrying a graduate student often means supporting a graduate student. Once that student has finished his or her academic program, a new problem appears.

For those who received doctoral degrees in 2003, it had taken a median span of 10.1 years to progress from a bachelor’s degree to a doctorate. Imagine that you marry someone while you are in the early stages of a doctoral program. In the time that you spend working toward your PhD, your spouse may go through a series of promotions into a nice position at his or her company. Upon graduating, you will be thrilled to land a job in your specialized field on the other side of the country (see Reason 16). Your years of work, after all, have been spent in a discipline in which few jobs will ever open, and in an extremely competitive academic job market. Unfortunately, your spouse’s company is in an industry that has no presence in that part of the country. Do you ask your supporting spouse to abandon a position (and salary) that has also been the result of years of work, so that he or she can follow you to an entry-level position?
