I am working on an article on relationships and marriages. In my part of the world marriage feels like punishment on the female gender. In the days of old as I learnt, it was the responsibility of the man to provide and protect the family but in today’s society, men relax and have the women do almost everything. I observed this most in Nigeria or African. women grow old faster once married. I take instances from my neighbours, family and the society. The man on any day wakes up, take his bath, dress up, eat and off to work if he has one. The woman is the cook, launder, housekeeper, nanny, hand lady, errand girl, cleaner, and she must be working etc. just name it and she must not complain, she must not be tired. For real this is happening don’t think am just assuming. I see it live. Why is it so? I once asked a man in this case, why he maltreats his wife like a slave and he said no reasonable man is allowed to do house chores or assist in anything. The work of the man is to bring money that’s all. Can this be true? Will you like your sisters, daughters, neighbours, friend be treated badly in the name of marriage? Let’s talk. No abuses or insult please. I need soul lifting contribution.
There are sadly some parts of the world and cultures where marriage is still essentially modern day slavery and women are treated as second-class citizens that are basically just expected to stay at home and cook and clean and have sex with their husbands when they want it and that's about it. I don't think there's any evidence to suggest that women age more in marriage, though. I'm sure the men who are the breadwinners and go out and work hard all day also feel the stress of this expectation on them (though I'm not discounting how hard it is to raise children and be the home-maker).
In the West many people would argue the roles the OP describes are reversed and they feel like the women get to relax while the men work. Of course this is a generalization, but it does not make it inaccurate. There are many social and economic differences that cause these results in both places.
I agree with that this used to be the case, but luckily attitudes have changed very fast over the past few decades and now men and women are mostly equal on this front (at least in my country), though obviously some women do choose to stay at home and be 'housewives' and look after the children and so on. I have no issue with that as long as it's their choice and there's no expectation on them. I have no issue with a man staying at home and doing this role instead either.
IMO marriage was originally conceived of to build society, and a lot of evidence supports this premise.
I don't agree with this. Marriage was essentially created for men to claim ownership of "their" property ie wives, not for the betterment of society. I think marriage is born out of male insecurity and wanting some kind of contract that legally ties the women to them forever. I think a lot of oppression of women is born out of male insecurity and them not being able to handle the thought of anyone 'messing' with "their" property/wife. Why do women in some Muslim countries wear burka or niqabs? Those were rules imposed by the men of society because they want to keep "their" women covered so no other men get any ideas and are enticed by a bit of skin and try have their way with their wife. Once that women is married then they become the property of that man and the only person who should lay eyes on them are their husbands and that's a very sad state of affairs
