Well, not quite. A very slight survival difference is enough to drive evolution. For example a 1/10,000 decrease in survivability will result in the trait being reduced to about a third of its initial incidence in 10,000 generations or perhaps 200k years in humans. And obviously, larger than necessary breasts are bad for posture, running and consume resources. Thus there must be some advantages for them, such as sexual selection via the handicap principle, and if they can also store fat in addition to be attractive to males, so much the better.

In a nutshell, women have large breasts not because they are easy, but because they are hard, and for the same reasons.
