In the great 80s comedy Night Shift, there is a scene where Michael Keaton is driving down what appears to be the West Side Highway in New York in a brand new Cadillac with "Jumpin' Jack Flash" blaring from the speakers. In a bid to impress a mildly terrified Henry Winkler, Keaton attempts to demonstrate just how dark the window tinting is by driving next to a police car and, among other things, flipping them off and pretending to smoke a joint. As he does this he says, "We got teenage girls, the place is full of broads in here."
Point is, Keaton's character wanted to be a rock star and the closest he could get was pimp (or Love Broker if you prefer). He wanted to be a rock star because it is commonly known that they get the girls and many of those girls are teenagers.
We've all become accustomed to bad behavior by musicians -- it isn't called "sex, drugs and rock and roll" for nothing -- and it often involves young women, some innocent and impressionable, some not so much. Hell, Pamela Des Barres made a living off of the groupie lifestyle. She even refers to herself now as a "groupie guru." Shudder.
