I think very few people are really thinking that exploitation of the individuals is the issue here. I would assume that the individuals are making a free choice to do this for money, knowing exactly what they’re doing.
Equally, nobody is claiming that anyone will see a scene such as the above and say “Oh right, so that’s how it works then, the men are th important ones and the women are there to do nothing except look pretty.”
But in the context of there being so much crap like this around, and the historical (and current) inequality in roles and perceptions, it’s an unnecessary contributor to the perpetuation of those unfair, unhealthy and also downright stupid ways of thinking.
To my mind this is a kind of casual sexism. As has been said before, in an ideal world it would be so trivial that it just doesn’t matter, but we’re still a long way from there.
