That’s kinda fair, but only if not looking at context. Unions represent the will/votes of the workers, and in the past women’s rights were culturally looked down on. In the present day equality is a more widespread cultural view so unions now would reflect that, at least in areas that do. So essentially unions are only as good as the current majority ethics of the workers within them.

Don’t forget the slavery profits from prisoners via the 13th amendments second clause.
