I think you're spot on, but I think that parents of Millenials saw these changes as well and made sure to try to set up their children for a working life regardless of gender. There's still a stigma against stay at home dads though, so while traditionally male gender roles have become more open to women, traditionally female gender roles accepting of men have lagged a bit. It's definitely not a case where equality of opportunity has been reached, however there has been progress and we are still moving forward.
