Exploitation: using someone for profit.
See, you don't have to feel exploited to be exploited. CBS is only interested in ratings and bikinis mean ratings so, yes, they are exploiting the women.
But I wasn't saying the women would slap the staff because they feel exploited, they would do so because they were left in the cold with no clothes. See, not every fan of the show knows what production is capable of doing. I'm not talking about recruits (good for them if they are tricked due to their lack of knowledge) I'm talking of the 99% of fans that never come on line, just watch the episodes. They don't know that production goes through their lugage, putting aside most of their clothes, leaving them only with those skimpy outfits. Did you see a single pair of pants in the women's shelter? I didn't.
Anyway, even if they knew what was going to happen, when you are presented with a 1 in 18 chance to win a million, you accept some things that normally would be unacceptable.
As for inadequate shelter, do you know that there are restriction on what they can build? For example, the shelter has to be opened on 3 sides so that the cameras can get the desired shots. Pretty hard to cut the wind when you are only allowed 1 wall.
