That might be part, but there are even simpler explanations. Taller people make significantly more money per inch. Why that is, who knows, but just by itself it can explain around half the wage gap - before correction. In other words, after correction, if you also correct for height, then women make more than men.
Of course no one should make more money just because they are taller, but that's the reality. No one seems interested to try to correct this, though, because it's not obviously tied to any popular political movements.
