I'd argue three reasons. First, airlines usually recruit military pilots, since the government was kind enough to invest $500k or more to train them as pilots.

I'd argue three reasons. First, airlines usually recruit military pilots, since the government was kind enough to invest $500k or more to train them as pilots. Second, the era of airline pilots being a glamorous job is over. When major airlines add pilots, they usually come from a layoff pool. Third, mothers are usually primary caregivers for their children. The schedule for a pilot is awful relative to the level of education required. It only really works if your spouse is in a job with very flexible hours.
