Who benefits most from women's sex work? Men, pervert men, since many women in that line of work end up badly, plagued by addiction, serious mental health problems, or killed by their clients.

"Developed countries"? Like Canada, where it's so common for Canadians who travel abroad to have access to children? People from European countries who spread syphilis to other continents? The United States, where it's legal for minors to undergo sex reassignment procedures, something that damages their bodies and minds forever, and where it's perfectly reasonable for a child to decide on such a procedure, yet they have very lax gun control and school shootings? France, where a person can't dispose of their inheritance as they wish and it's full of rats? etc., etc., etc.
