My point about not wanting any female in my family in the business is academic: none wanted it.
That some make millions is well documented, as are the 'train-wrecks' too. My personal opinion isn't really coloured by the drugs, because I think that that depends on the individual to resist or otherwise; more, I think about the unpleasantness that can come from clients who use their power for personal, non-business advantage, and there are many; it even happens to snappers, never mind models where sex comes into the game on top of everything else.
Really, I sort of dislike the idea of a business where you can't metaphorically close the shop and go home to your own, private life without someone wanting a piece of you out of hours...
I used to face that at weekends: Friday afternoon the 'phone would ring with requests (?) for prints first thing Monday. Those ADs didn't work weekends. And often they didn't need the pics on Monday, either: I distinctly remember going back later in the week to an office and the shots were still lying on the desk, in the glassine envelope where they'd been left when I delivered them. It's about demonstrating power. But of course, you knew that from life already.
