This is questionable. Highly populous countries have worse living conditions than moderately populous ones, currently.

There does not look to be a strong correlation between population density and income, at least on a log-log scale across countries. But I would guess that these numbers hide a trend for cities to be richer than rural areas (subsistence farming etc).

Highly populous countries were colonized and robbed off their resources until recently.

Better living conditions cost more money per family, which leads to less children.
