I've posted on here before about it, but what you are describing is a generational delay between the changing of male+female roles.
Women (and some men) campaigned for a change of female societal roles, so that women had equal standing to men in professional/career terms. It took a century, but it has now (in my opinion) been achieved. Women under 35 now earn more than men on average, and the remaining inequality tends to fall in biological areas that are challenging to solve e.g. childbirth.
There is still inequality in the higher levels of employment, mangers, CEOs, bosses etc. But that is largely due to how long these changes take to filter through. Most senior positions today are held by people in their 50s-60s, who spent the majority of their career in a society that was still skewed heavily towards men. It will take time for these changes to filter upwards, and for the girls born today in a more equal world to climb and reach those levels.
So, you have women actively pushing for equality in the workplace...
Yet over those hundred years are men pushing for equality in the home?
Not really.. they didn't want it at all. It was an easy sell to give men "accept equality/female rights, and your wives will now go and earn money!!!" that worked for a lot of middle class men. But they never wanted equality in the other direction.
So instead they (as a generalized group) have gradually increased how much they do at home to slightly compensate for the increased income that women provide. But up until the last 10-15 years, the vast majority of them have still out-earned their wives, so they can still say "well I earn more".
Now though we have hit the point where a substantial amount of women are out-earning men, it is becoming a problem. As is so observable on here. It is so plainly unfair to women and to any rational outsider looking at a relationship.
But people's habits are very hard to change. And to defend men, it really isn't easy to alter how you view the world, yourself, and your role in your family. Most of the women today grew up watching their mums work and do housework, and being told to be independent and do both. Most of the men today, didn't. They grew up watching their fathers work and do nothing else, and with the idea that as long as they earn, and do a bit of "help" with the kids/house, = equals = they are good dads and husbands.
Changing those fundamental ideas are hard.
So in my opinion there is going to be a generational delay. A middle generation of "useless" husbands who earn less and do less and ruin their marriages.
However, I do believe that the next generation of men, who grow up in a world where women earn as much or more at times, will be forced to alter their view of what a man/dad/husband is - and we will eventually see a balancing of roles. It will just take a generation for it to happen.
