The backlash begins as soon as there is any resistance from a slave to slavery, and in fact as soon as there is such a thought in the mind of the slave owners or slave drivers, which happens long before the thought occurs to the slaves even as individuals much less as a group. This phenomena, the the fear of losing sources of unpaid overworked certain labour, source of prosperity of owners, expalins the torture and atrocities against any slave groups, races, and even women, the gender that was enslaved last few centuries in some parts of the world.
That this was not always so - not everywhere - is clear from the fact that when money is not a few signs on a piece of paper or a computer screen, when money is not even coins so much as real wealth, in terms of what helps life really - farms and harvests, cattle and milk and transport, manpower that can work and protect, women power that can work and organise and feed and reproduce - then women are not deprived, cheated other halfs, they really are the providers of wealth and entirely necessary.
What is more wealth in this form cannnot be taken away from homestead and so the community holds together, women cannot be cheated as easily as when corporates pay men and have an unwritten unspoken agreement that the men can in fact cheat wives out of the partnership by hiding or even worse, proclaiming it all as his earning, his property. Then, when women are no longer needed except for the sexual slavery and house cleaning drudgery, is when they became replaceable slaves and had to be kept down so the physically stronger gender could continue to cheat them.
The vows of marriage even in church include "with my worldly goods I thee endow, with my body I thee worship" and it is now forgotten even by those who claim to be churchgoing believing worshippers.
The backlash began as soon as there was slavery of women, and this book recognises it when it came to level of media in all its forms - ads, films, teleserials, and other corporate inflenced parts of world of communications.
