If this writeup on that book is accurate, sounds like a steaming load of horseshit. Especially noted is that ridiculous figure of it taking $300,000 a year to raise a child. I see all sorts of these absurd lifetime cost figures thrown around in these sorts of discussion, inevitably by people who have never had kids. I have two and rounding up I think they are only costing me something like 2k per year (and I don't claim them on my taxes, so I don't get reimbursed for that). Now, that's only a dollar figure, and certainly doesn't take into account the various things my wife and I might like to do that we can't or can't do as much, like going out to eat/a movie as much etc.
The trade off is well worth it imo.
There are not "too many people", but from the point of view of most people, all the rest do more or less "suck". This consistency would indicate that the problem is just as much with ourselves and the culture as it is with "everyone else".
I don't advocate just popping out babies for the sake of procreation itself, but lending our lives ultimately to some "Idiocracy" outcome is certainly not admirable.
