“capitalists aren’t inherently evil capitalism makes them that way” and capitalism was created by whom and for what purpose again exactly?
male dominance is not believed to have always existed in society; neither is the separation of people into classes with overwhelming ownership over society’s wealth/means of creating wealth (this pre-dates the creation of the capitalist and capitalism, of course, there have been many owning classes), and those who by and large do not (at the least, not significantly enough to change their class position in that society). the creation of an early form of socioeconomic class became possible after certain societies went from being nomadic hunter-gatherers to sedentary agriculturalists, a change made possible by advent of the holocene and necessary in some parts of the world due to the depletion of natural resources to sustain the community.
in a similar way, the advent of male dominance is believed to have largely come into existence as a defining feature of human societies during this transition to sedentary, or semi-sedentary, agriculture. there are various theories; I find Gerda Lerner’s to be most persuasive, in that once humans began experimenting not with matrilocality (men move into their female partner’s village and home), but patrilocality (wife moves into husband’s village and home), — a choice that was, again, simply one of the numerous available options human societies could choose at the time, and not a deliberate ploy on the part of men to ensure domination or women to ensure they were dominated (why would women ever have allowed this to happen if that were the case, if they could see male societal dominance coming?) — a choice which came with the unintended consequence that now, should a man ever try and exercise his greater physical strength over a woman to get her to do what he pleases, there would be no other relatives of the woman in that community to take her part or defend her. this began a precedent. men began to learn that now conditions made it possible to use their physical dominance to control their social group, and significantly, the women within it. this also made it possible for men to have some control over their group’s numbers and reproduction in competition with other nearby groups, something made possible by this new ability to control the movements and actions of women without consequence.
there are more theories than just this, but they mostly agree on the moment in which gender — meaning here, sociohistorically constructed sex roles and prescriptions — became possible. certainly hunter-gatherers are believed to have had some form of the sexual division of labour necessitated by the harshness of their environment and reproductive necessities (most babies, unsurprisingly, died at this time in history), but they are not believed to have had, by and large, sex roles that were hierarchical, or sex hierarchy, of which patriarchy is one form. this isn’t to say no man ever mistreated a woman in nomadic hunter-gatherer groups, but the social and material conditions of these groups didn’t allow such individual misbehaviour/aberrations from the norm to become an organisational principle of their society.
similarly, nomadic groups did sometimes have individuals who were greedy or didn’t pull their weight, especially in times of food shortage or hardship, but conditions didn’t yet exist for this behaviour to not be managed and potentially punished by the rest of the group, as it was seen as a direct threat in some cases to group wellbeing and survival. in some cases, as individuals didn’t own significant property individually, as this belonged to the collective, everyone else could just kick you out. this isn’t as possible later on when those who are greedy actually own a larger part of the food supply as they farmed it, etc. then those individuals had much more decisive control over the group.
