Or, lollygag, you will be trying to discuss with other women what a term means and a man will come along and tell you you have got it all wrong.
Let's look at your example of coal-mining, shall we? Massive industry a hundred years ago. Men went down the mines, they were the waged labourers, women stayed at home and looked after the children, that is once they had survived childbirth, which was, in those days, more dangerous than going down the mines (higher levels of maternal mortality than death in the mines) with what money their men gave them. Once a man had finished his shift, he was done, his wife washed his dirty clothes, cooked his dinner, looked after the children so he was not disturbed and so on, her shift did not end. All the man had to do was provide some money for her to run house and home, but often the pay packet would be pissed down the pub before she saw it, and the man would come home and treat her to a beating.
Whatever you see now has historical roots. The reasons you see men in those jobs are historical, for the same reasons you see women in certain jobs (usually caring, nurturing, domestic jobs, if you are talking working class labour). Which do you reckon gets paid more, and who do you reckon finds it easier to get to work once children come along?
