Ohnomoomoos , unfortunately men have always used prostitutes and treated women badly.
However, there did used to exist a different culture - a culture that was very repressive in lots of ways and has rightly been reformed since the Second World War, giving women and people of different sexual orientations rights. Nevertheless, this moral order established the family and romantic courtship as bulwarks to prevent moral anarchy. Taboos existed. Prostitution existed but it was not considered normal and acceptable. Extreme pornography existed underground, but even mild forms of nudity were illegal in mainstream society.
However, in the 1960's everything changed. An alliance of left wing sexual radicals and right wing market libertarians succeeded in destroying the family and the idea of monogamous love and duty that underpinned it. One by one sexual taboos were removed. Although the sexual revolution had been spearheaded by feminists, women became more commodified in this culture than ever before. Markets in prostitution, pornography, sex toys and expanded. This was not just a left wing revolution, but very much a right wing return to the cult of power and self-interest - a rejection of the secular ideal of a just society. Then in the 1990's came the fullest realisation of the liberal dream: the internet. A deregulated, global communication network meant pornography and other sex industries could be accessible to millions without the interference of governments. In this market, there are no taboos. Every desire or fetish, no matter how dark or barbaric, could be catered for in a few clicks. Rather than meet people in physical spaces where intimacy could be developed, people have become accustomed to choosing sexual partners from an array of options on a screen. This is similar to how a man might choose a prostitute, so many men who wouldn't have considered paying for sex before, go that extra step. After all 'if it feels good, do it' eh? Moral values, love and commitment play no part in this new world: only self-gratification.
I predict this will get worse. In time, it could be considered normal for people to watch the rape of children, or people being tortured and murdered, for pleasure. Technological aids such as sex robots and VR simulations of every kind of fantasy will also be seen as normal.
I don't mean to do the 'women do it too' thing, but I see no reason why at some point women will not use sex robots too, or enjoy sickening porn in equal numbers to men. The internet and technology will give women the freedom to do all the things that they haven't been given to do before, because they've been taught that women aren't like that. In the future they will have licence to be as sociopathic as men. It will just take time for them to catch up.
Monogamous love - having sex with someone because you care for them - will seem to the men and women of the future with their fuck buddies and fuck machines as archaic as the divine right of kings.
