In the old days, a constant supply of new people was needed to work the fields, die in wars, and everything else.  Now, wars are not fought by numbers, nor are numerous people needed to work field, and the carrying capacity of the planet can't really handle more people anyway.  Most K-selection whites and asians will naturally reduce their numbers so no type of eugenics scheme is actually required to kill everyone off or anything, but the R-selection groups like Africans, Hondurans, and whatever, will keep reproducing out of control and have to be dealt with in some manner.

The other side effect is that what made women some type of valuable resource in the past no longer exists anymore since we don't need an infinite stream of exponentially increasing people churned out, but in their own brains they still retain the obnoxious attitude that their lives are far more valuable than everyone else and men's lives have no value.  In reality, their world view is 100% opposite of reality and men's lives have more value now.  Women are currently standing at the peak of an entitlement cliff with nowhere to go except way down.
