Not read the full thread, but I am a feminist and I do say this sometimes. My reasons are that when you're looking at a household budget, you need to weigh up how much each person going out to work "costs" the household. Given that women are a) usually the lower earner, b) have just been off on mat leave and so earning even less, c) is likely to be pushed aside immediately upon returning to work because they are a woman with a baby (even if they dont want to be), the father's job is the often the safer bet in that moment.
Here, full-time childcare for 2 children under 3 is £2,400 a month. Most people, certainly most (young) women can't afford that out of their take-home pay. So the "family budget" is better off without the lower earner working.
Of course, this is only temporary, as costs will drop a bit once one child turns 3. But then you need to have a parent available to do pickups at awkward times. Or pay a fortune for wraparound care.
But realistically, as long as childcare costs what it does then many women will struggle to work.
It is a feminist issue. The "fault" is not with individual women trying to balance family budgets, nor is the fault with feminists who recognise the environment these individual decisions are made in and 'deduct childcare only from women's salaries'. The fault is with the system and society that backs individual women into this corner, then blames their individual choices for their inability to get themselves out of that situation.
In my ideal world, childcare would be more heavily subsidised and employers should start expecting men to be an equal parent who also has childcare responsibilities.
Both my DH and I work FT, flexibly, and share childcare. We each have jobs that pay relatively well and we are trying to maintain this balance, but it's tough. And I'm lucky that we can make this choice. I know most can't.
