I agree and disagree at the same time. If your spouse is a white collar professional, there is a likelihood (whether it's high or low depends on the job, of course) that they might have to relocate for promotion. Having the ability to commute invariably affords that spouse the ability to realize their professional aspirations without a landslide compromise of the pilot's career. QOL compromise? Of course. However, I several couples that seem quite happy and content because a move wasn't a career-ender for one of the individuals.
