I have recently heard the opposite, at least as far as women goes. For a lot of women, especially mothers, being a single mother is a whole lot easier than being a married mother, since there is one less person in the house they have to take care of. A whole lot of men were not socialized to be actual contributing partners, which loops back around into the prime reason why a lot of men are having a hard time dating these days, because a whole lot of women are sick of putting up with that, and are instead looking for men who will contribute an equal amount of housework, cooking, emotional labour, etc.
Especially given that it's not broadly reasonable for a single partner to go out and earn enough money at one job to support both people (let alone a family), it's no longer acceptable for men to not contribute around the house equally.
Of course this is an average, so it's possible in some families women are working more, and in other families men are working more.
But modern political sensibilities filter those stories so that you'll only hear those confirming a certain bias (men bad), which distorts the overall picture, which is on average equal work.
Are you really believing that women are happier alone because men don't mop the floor?
I married a single mother, I don't mop the floor or cook everyday. My duties are stuff she cannot do like taking care of the house or repairing cars/bike.
I definitely do less than my wife for the household on a daily basis but I bring the money and a shelter. She is a 1000 times happier than being alone.
Straw man argument. If you and your wife feel like you're both contributing equally to your partnership, well, that's not what I'm talking about.
But there are absolutely cases out there where the women work as much as the men they're with, bring in as much money and shelter, and then are expected to do the housework, child-rearing, emotional labour, etc as well. I have heard from them and I have known them. And I absolutely believe them.
So they are complaining that their partner do less than them and want equality on household chores, whatever that means because we are not genetically equal and men will never feel the pain of labour.
That is very different than stating that "For a lot of women, especially mothers, being a single mother is a whole lot easier than being a married mother, since there is one less person in the house they have to take care of". Having seen all the work involved for a single mother, I really doubt that it is "a whole lot easier". It is a 24/7 job where you cannot stop a minute.
Breakdown of community and extended family has also contributed. The amount of chores needed to raise a modern family with two working parents and no help, even factoring in childcare, is insane
