Advertising gives the people what they want. Men and women both want to look at attractive young women. The industry complies, and realizes that models are starting to look busted and fucked up at an earlier age from starting the CC earlier, so they lower their age target to what sells the most, which is "a girl untainted by the world". The post-wall cows throw a temper tantrum.

The filmmakers

Then the women who were once the center of attention hit the wall, and create this sob story documentary to make men feel guilty about being attracted to the young models. Which they once were in their prime. Hypocrisy at it's finest.
