but none of us have to give up work or move into a partners house. None of us have to have children either
Nope, nobody has to. Men don’t have to be the breadwinners either.
But out society still isn’t equal in that regard- gender pay gaps, seeing women as the childcarers, men as lesser if they choose to. So inevitably women do give up work, often not seeing the long term costs to pension and independence. “Childcare means it’s not worth me working”, or they take on the lions share of wifework, so full time employment, plus children, plus house stuff, while husband fulfills his duty by going to work.
Plus there is still a cachet to being married- ask women why they change their names and use Mrs- “because I’m proud to be his wife”.
I don’t agree. Marriage for me as a homeowner and higher earner, i would be shafted on divorce. Yet still I get people tell me i need marriage “for protection”, as automatically they assume I, as the woman, cannot possibly be financially better off. Or that being an unmarried mother is somehow frowned upon.
And yes, there are alternatives. But it’s easier, and can be cheaper to get married than to have all the documents drawn up legally. Plus, as I said there’s the big party, dress, admiring guests etc…
