There has been research that shows that men who exploit young women / girls aren't necessarily "gangs" but in fact have a shared area of work. So for instance mini cab drivers, who are more likely to be aware of who is out and about in cities. And sadly youth groups, were predators can find out who is more vulnerable, and so on.
The 2 / 3 better known instance in London where local boroughs (all Labour run) covered up abuse and exploitation of vulnerable girls were all white working class men who knew it other from their work for the council, or the housing estate they lived on.
I am not saying this article is perfect, and I think would have been better not focusing so much about the fact that in Rotheram the common factor, althought outwardly was race, there was other commonality.
And what she also tried to point out was / is that a the same time as the tabloids are screaming headlines about race, children were / are being pimped and exploited to rich white men, by other white men. Even the church has history of exploiting orphaned children in their care. And most of these are covered up by the establishment.
The common factor is, as said by previous posters, men of whatever class or race, who are happy to exploit young women who are somehow in a position of absolute vulnerability, even within familes. Not so long ago news papers reported about 2 young women in France. Both from supposedly educated arty type families, but were pimped out to leading literary figures. ie the famlies placed being part of a particular circle as of such important they prostituted their daughters.
So the primary problem is men and male culture in all sections of society.
But made worse that if there ever was a time that social services actually provided support to young women forced to live on the streets so that they aren't taken advantage of, there no longer seems to be a consistently well funded, well run, fully staffed service to do this.
And whilst feminist campaigning has had some impact, ie stating what it is, child abuse, overall society as a whole, governed as it is by men, has not changed that much.
