The ability of one spouse to find employment is not always the only key attribute. Often there are other factors which must be considered before a move.
There are many reasons that someone can be tied to a geographical location, including by having a job, taking care of a sick family member (often moving old people or moving them into an openly dependent position can trigger a downhill slide), or being enrolled in an educational program. In these cases the inability of the other partner to get a job
there may not be more important than the existing tie.
Put another way, being in an equal relationship means that either person's needs may take priority over the other's depending on a natural give and take.
Now I don't know Norm's situation, but this one strikes home to me given that in the next year I may have to move 1-2 times for my wife, and if I can't find employment it is, "Oh shit, see if we can borrow money." (The issue here being that my wife's educational prospects trump my current employment as a concern.)
Cheers,
