I don’t buy into the rational/market/economics style theory that people choose to do tasks based on what they think will be more profitable.
People choose to do things because they enjoy doing them, and people enjoy doing things more when they’re good at the task. If girls have better language skills, they will naturally gravitate to those kinds of tasks because they like them better, which will reinforce their skills, in a cycle. The same can be said for boys who like to do things and naturally gravitate to/reinforce those skills. Eventually you have people who are good at doing different things, because the initial advantage/preference gave them a tendency to move in a particular direction.
