> Pay gap for men and women only starts mid career. Is a big red flag for me. You can't control for age. This subject is generational. The underpaid 40 year old women in 2010, are the same underpaid 50 year old women now. We didn't get a new group to sample. We can talk about 'the average 30 year old' within one generation. We can talk about 'the average 30 year old' across time. But they are easily mixed up and mean very different things. 'mid career' is not a useful phrase. --- In the same vein, the middle is steadily shifting as our pension age shifts from one generation to the next.
