Elaborate please? Or clarify?

There are few times when organisms can pioneer new niches. For the most part, they balance on complex food chains with little elasticity. For most complex organisms holds that if they cannot put their children into the same environmental conditions as themselves, they may die.

Does that correspond to the intuition that the number of children of a first world family is strongly influenced not by the threat of starvation, but by the parents' capacity to sustain the socioeconomic status of the next generation? And is that perhaps universally true?

I think that may be part of the equation but I know parts of the first world which use this only to guide between say 2, 3 or 4 children independent of projected future status. Ever been to Fort Worth, or St. Louis, or San Antonio?So not universal, imo.

I think that the socioeconomic identification may be a community if you are religious. Most urban people just mix that up with income and education brackets, because that is what defines their community access.

I think we agree it's only the universal part I have trouble with e.g at the other end of income billionaires don't seem to have grossly disproportionate large broods, do they? Human UNIVERSAL is a high hurdle! Maybe? Maybe in the future?

Selection bias. People being billionaires are often single mindedly interested in and busy with being billionaires.

Even on the East Coast very wealthy families are moderarate in size in my experience.

Number of children seems to be J shaped with family income. The J becomes less pronounced when almost everyone is poor.

Agreed. That is a description of current state. Absent new technologies/policies which might alter that J shape significantly.
