I enjoyed it. I think the storytelling is very good, though I agree about the end.
However, the more I think about it the less plausible I find it that men would agree in large numbers to a method of control that renders their wives unable not only to earn money but also to fulfil the vast majority of their job as sahms and wives.
It might have been more plausible in a world where women spent the vast majority of their day performing physical labour, but that's not what our world, where this book is set, is like.
I am a SAHM. My life is mostly not spent cleaning and cooking, though obviously I do some of that. If I am going to have a speech limiting bracelet thingy put on then sorry dh, you're taking ds1 to his hospital appointment for his broken arm. You're sorting out the bin collection issues with the council. You're trying to find a new garden bench online and reading all the reviews and then buying it and putting it together because soz, I can't read the instructions. You're sorting out the kids' food tech ingredients. Oh, and I won't be doing any emotional labour other than smiling and nodding so if you have had a bad day at work I am not going to be able to reassure you about it, and you will also have to deal with the boys' friendship and other school issues and help with all the homework.
Luckily our boys are old enough to have already learned to talk and read but all that chatting mothers and other carers do to young kids won't be happening so the language development of the next generation is going to be pretty fucked.
In sum, despite its aims, this seemed to me to be a profoundly anti-feminist book because the author seemed to have no comprehension of or interest in what women actually do.
The concept was brilliant - but I think she needed to work backwards from the concept and build a world in which it would have been plausible. Eg a world without companionate marriage, without labour saving devices, with different patterns of consumption, with a different system of child rearing.
Even if we accept (which I don't) that it is plausible so many men would agree to torture their wives, it felt like a massive plot hole to me that they would be prepared to do it when it would make their own lives so much harder.
