Does having podium girls mean that the men who are watching them will objectify women, treating them worse, and lead to a general degredation in the rights and treatment of women in the world?
Would the disposal of podium girls mean the opposite, that the cause of women would be gernally improved?
I'll build a bit of a straw man here - for the "booth babe" version, then yes, they are meant to both objectify the women (willing though they may be), and manipulate or titillate the male observer. I actually resent the suggestion that I'll buy something because of its association with a scantily clad woman. Even the scientific instrument resellers sent a rep round the labs who appeared to be chosen for her looks and dress sense, rather than her knowledge of the technology or science!
I'm a little less concerned about "respectably dressed" podium girls, as that moves the question from exploiting sexuality to exploiting beauty. The latter has its own problems (unrealistic expectations, self-image, etc), but at least we've moved away from lust.
Put it like this - I don't want my children deliberately setting out to parade their sexuality, and I want them to have healthy body images, but I'm happy that they should take appropriate care of their appearance and bodies.
