That's a different point again then. But still too generalised.
For one use of the term 'plan' is significant here. Women don't necessarily plan to be the lower earner or take a disproportionate share of childcare. There are a whole load of societal factors at play there. I was the higher earner before being pushed out of my job due to maternity discrimination, as an example.
It's also not simply about how much money you make, because higher earning women are disproportionately paired with higher earning men. A higher earning woman with DC may still very well be the more financially vulnerable of the two. We won't get anywhere if we consider only the woman's earning in isolation.
Agree 100% on the Disney princess point.
Basically, women do need to evaluate the situation and not generalise. I am absolutely, fully on board with that. There are absolutely situations where marriage is a disadvantage, especially if you have DC already from a prior relationship and want to protect assets for them.
But part of that situation is that a majority of us are the financially weaker party when in a relationship with a man, and that there are wider societal and cultural factors shaping that which cannot be waved away. All women are at some risk of being impacted by these. Simply being of the sex who get pregnant is in itself a risk factor for being made poorer. We could do with more understanding of this, not less.
There is also the need to consider what happens on death too, and most marriages end with bereavement not divorce. For obvious reasons, this tends to be more pressing the older someone gets, and people who didn't want to marry often start marrying or registering a CP once they get to a certain age and realise they prefer the way the law treats bereaved spouses to the way the law treats bereaved cohabitants. Unfortunately, we don't get advance warning of when we're going to die.
