"The erroneous perception is that "anyone can be a bin man". It's not true - you really need to be strong"
this kind of view is the heart of a lot of the reasons for gender inequality.
The pure academic example is the society that needs 40 hairdressers, 40 garage workers and 40 firefighters (lots of burning bras, obviously). The society has 60 women and 60 men in the available workforce.
Result? Culturally, the 60 women are conditioned to want to be hairdressers - you have 60 of them chasing 40 jobs. Result? the salary for hairdressers drops until demand equals supply and 20 women drop out thinking "it is not worth it, I may as well not work". This leaves 80 'male' jobs to share amongst the 60 men. Again because of supply/demand, the jobs cannot get filled and the salary for the mechanics and the firefighters rises in an ongoing spiral.
So, this is society in practice, because you have/had (you choose the tense, I maintain 'have' is the correct one) more women available for women-type jobs and not enough men available for men-type jobs. To some extent the way the UK has bent to correct this has to allow certain industries (such as teaching) to shift from being male/neutral to being female. But generally the ones that have shifted are the ones that are not considered to be 'status' type careers (and, even when they are, you see their status and perceived value dropping as they shift - just look at the difference in how headteachers were valued 40 years ago compared to today). Where the career itself is highly valued (judges, surgeons, industry leaders) the competitive nature keeps the girls out. And as you head up the poles in these types of industries the leaders see no reason to remove the barriers. So you still have key positions where you can only get on if you put in 100 hours a week (financial services) or where you have to travel at the drop of a hat (politics, industry), or where your career progression is highly dependent on your networking abilities (ie the golf club, the freemasons, yada yada). And there is no incentive whatsoever to remove those barriers, because to do so would require those at the top to say "We are not the best type of people to be running these industries" It is like asking turkeys to vote for Xmas. When you have been in board meetings and seen with your own eyes another woman's extremely valid viewpoint being totally dismissed by the men round the table,you find it very difficult indeed to dismiss sexism as being just down to women wanting part-time/less demanding roles. I have seen extremely successful women in very valued high-earning jobs, but they have generally had to 'build up their testosterone' to do so and they themselves are not normally supportive of women climbing behind them, because they also learn to value assertiveness and 'strength of character' over other skills. The good strong powerful woman who is valued for her skills at empathy, negotiation, compassion, diplomacy? A myth still. And that absolutely sucks.
Asking whether it is right for women to opt out, or whether women should stay at home are both topics for other threads. As is any discussion of the value of being at home and raising your children yourself. The point of this thread is to point out that when people are in the same profession, at the same level, with the same skills and the same commitment, they are still paid less and valued less than the guy sat next to them. And I have seen this with my own eyes. And I have seen bosses pay assertive but not very good men the same bonuses as brilliant but not so aggressive women, simply because it is less stress for them to cut the bonus pool in any other way. And it really really really sucks. And it sucks even more when people say that women can go off and start their own brilliant businesses when this happens and then work their hours to suit them. Great in theory, but in practice our industries lose the best people, and most start-ups do not get further than the cottage-industry level which means that the women still get oppressed (much as I hate to use that word) in terms of their political/economic power.
The gender thing infuriates me, I have seen it, I have studied an MSc and conducted independent research around it and I have had to shift careers to bypass it at times too. And anyone who says it doesn't exist because of X,Y or Z reason, are doing a very serious diservice to their own daughters.
