It's unclear to me how this is evidence of a patriarchy. Women are able to choose to work less yet still enjoy the financial benefits of the men working. This sounds like a matriarchy. There is virtually no stigma when a mother chooses to work, but a father who doesn't is called a dead-beat. It certainly doesn't feel like a privilege to know that my families entire financial future means I must work until I'm 65. I don't work because it's so much fun.
