Every time I’ve looked into it, pay gaps for same role and same experience are very small, sometimes favoring women. And if anything, women are promoted faster in an attempt to diversify the management ranks.
1. Group A is literally paid less than Group B, for the same work. This is much less of an issue today than it used to be, but its still an issue.
2. Members of group A are promoted much less often than members of Group B, so while a Group A member in a high-earning position has commensurate pay to a member of Group B in the same position, there are simply fewer Group A members reaching that position. This is the more common, and frankly more pernicious, problem.
The very first link in the recommended google search says that only 25% of C-suite members are women, yet women make up 35% of all tech employees. In other words, a smaller percentage of women are even reaching the highest levels than men. That's pretty clearly the 2nd kind of wage gap. Now, that might because of selective promotion practices (which you discredit), but it might also be that women are laid off 60% more often than men, so they have to restart their seniority journey at a different company.
You can easily search "women in tech statistics 2024" and make your own conclusions.
My conclusion is that the gender gap in tech is not completely resolved.
