That was a read. Let's say that this is old and it has not aged well. From a 3rd wave feminist perspective, it's kinda terrible, actually. Some points the book tries to make are TERFy af, white-supremacist and, while claiming to be feminist, still misogynistic (though this could be debated based on the POV it's written in...).
There are some observations on how patriarchy and capitalism intersect to exploit women are well presented, but it's not further investigated. The chapters that touch on sex are downright horrible (especially considering consent within marriage, urgh). I would not recommend it unless you're actually looking for a text from that time period and know what you're getting into.
