It's very detrimental to society:
-It convinces women to be weight-conscious and bone-skinny when men aren't the least bit attracted to that
-It seems to permanently damage women's self-esteems. They sleep around too damn much.
-It causes shallowness because celebrities are often idolized just because of their status and power
-It causes women to buy useless, yet overpriced products
-Some women literally think that the higher priced a product is, the higher value it holds (certain brand names)
There's more, but these are the most relevant effects I've come across.
