The wording is pretty bloody awful, and has fallen into the same trap a lot of people do when they don't really understand the evolutionary process. In fairness, this has happened because there hasn't really been a good documentary series about it since the Naked Ape.
The fact that women have fatty breasts is not because men like them like that. Evolutionarily speaking, it is females that choose who to breed with, often based on subtle cues around the male surviving having higher than average amounts of testosterone, which causes a deleterious effect on male physiology. Because human females breed rarely, they must choose the best possible mates in order to produce the healthiest possible offspring with the best possible chance of surviving to be able to reproduce at least once.
Big boobs or otherwise has very little bearing on this.
So yes, men may well like boobs in some cultures, but that isn't why women have them.
