If this slump in fertility is generational (i.e., late X'er/Millennial families choosing to delay marriage/childbirth) couldn't this all sort itself out with higher birthrates among the 35-45 age cohort sometime in the near future? Basically, the median age at first-marriage has been moving later faster than older couples are popping out kids?
There is a reason women over 35 don't tend to have very many kids.
Anyway, this whole thing is only a problem within an economic system that demands perpetual expansion. Meanwhile, unending population growth causes ecological devastation. Socialism would solve this.
