How are you defining capitalism? These issues were all happening ten thousand years ago in Egyptian society which used a barter system instead of a monetary system; people were paid for their labor in food and cloth and there were slaves. I think the culprit you’re looking for is patriarchy. That’s the social system designed to support patrilineage, the tracking of inheritance and ancestry through the male line, which actually requires the oppression of women. The patriarchal social model also requires hierarchy and sex roles stereotypes. I think you’ll find if you really look that the excesses are driven by misguided male egos and female grasping for safety. Socialism with patriarchy will have the same inequality.
