Our nations last great decades long economic boom did not correlate to an increased birth rate, but with lower taxes.
Overall the human population of the Earth is increasing. It is not at all declining.
To think the gravest threat to humanity is declining birth rates is delusional.
There was, is and will be a ready supply of humanity ready to fill in the gap of those populations that decline to reproduce at a replacement rate. More a threat to their particular way of life than a threat to “humanity” - but once again that isn't the argument the author is making.
Nobody is talking about "huge birth rates."
We're simply talking about birth rates over 2.1.
The west, with the exception of the USA and Israel, is well below that number.
The Third World is rapidly approaching it, far more rapidly than the First World did, despite uninformed doomsayers' protestations to the contrary.
Once the global fertility rate is under 2.1, which will likely happen by 2050, populations will begin declining rapidly as the elderly die off, and life expectancy no longer increases.
There was, is and will be a ready supply of humanity ready to fill in the gap of those populations that decline to reproduce at a replacement rate.
Not if global fertility rates don't stop dropping precipitously. Which is the author's point.
More a threat to their particular way of life than a threat to humanity - but once again that isn't the argument the author is making.
I really do not think you grasp the argument the author (me) is making.
