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.
Now adays Ad agency ADs are working over the weekend. They all look nervous and tell you about teh coffee shop/brew pub/gallery they are going to open in order to avoid the stress.
