I find it quite interesting that a similar number of 50% of men who enter the teacher profession also leaves while the number for women is about half. In stark contrast however, the quote text, the theory on why men drops out of female dominated professions share nothing in common with the theories on why women leave male dominated.
In a 2009 report by the Swedish national agency, they argue that the reason why people drop out at a higher rate compared to the dominating gender is that the work culture integrate gender identity when there is unequal gender ratios, and the more a individual work and study, the more are they forced to either assimilate into that culture or quit. Compared to the argument about "lower chance of being promoted", a hostile culture seems much more likely as a root cause to high drop rate, and I would be surprised if culture crashes had no correlation with promotion rates.
