Well as you said yourself, these are cultural influences that come nature. Women have a lot of their roles in society due to genetics and so do men. It’s why a lot of societal norms are the same across the world. There’s of course certain cultural aspects which influence where people work that aren’t from that.

The majority of politicians in the western world are men for two main reasons. The first being the majority of the population being white. The second being a lot of politicians have been in their jobs for a long long time, people often re-elect the same person in their area again (in the U.K. we call these safe seats), allowing for those who were in politics 40 years ago when the social landscape was different to still be a large amount of the government. Despite this, the cabinet under the previous prime minister in the U.K. had 0 white men in it.

White and black are races in the way we use it to refer to humans, it’s easier than saying “Anglo-Saxon” or “Ethiopian”. Anyway, the races don’t have any notable mental or physical capabilities that are different due to race, but there are those due to socio economic reasons, but that’s a different kettle of fish that I’d rather not go into as I’d be here all day. The only reason I brought up race is it’s a area you see affirmative action get put in place for, which especially in the case of university and college admission has been proven to not just be discriminatory but also negative towards those that get in. This video explains it bette than I can.
