Indeed.
I will add the caveat that, in my experience, women who are high earners tend to continue doing the vast share of childcare and household admin/chores too. Even if that involves paying cleaners and childminders. It is still their responsibility.
I am sure there are some men who properly take on the supporting role to free up the higher earning woman, but I have never met one. I know some stay at home dads, who do nothing other than the school runs (thinking of one in particular). His wife still does all the organising, cleaning and household admin.
So women here saying that having a partner at home hasn't really helped them is probably true, but I think many men completely rely on their partners to do absolutely everything. Often while they are working themselves.
My mother had a good career which she gave up to raise us. My Dad had the 'big job' and moved us from promotion to promotion all round the country. Every time she put down roots and got a support system around, the rug was pulled.
She ended up leaving, restarting her career and did quite well by the time she retired. When they divorced, he was a nightmare and denied her any access to his pension (she agreed for a quiet life but hugely regrets this now).
She has absolutely hammered home with me and my sister the need to never be dependant on a man. To keep our careers at all costs.
Which may be why I'm a single parent!
