"There are those who assume that low education correlates with low intelligence. Bill Gates might have something to say on this subject. And the plumbers I have know have been reasonably witty folk.

I'm not sure you understand what correlation is.
A correlation between education and intelligence does not mean there aren't educated morons and intelligent people lacking degrees.
It's also a hell of a stretch to claim wealthy have more children without a whole lot of qualifying information.
Women without high school diplomas have the most children, women with high school educations but no college degrees have the second most children, women with degrees have less children across the board, but women with advanced degrees have more children than women with basic degrees. This is typically assumed to be because women with advanced degrees are more likely to be able to afford things like nannies, maids, daycare, etc.
While the most highly educated women are having more children than their slightly less educated peers it is not nearly large enough of an upswing to swing overall correlation in the sense that "more money = more children" is true.
Women without high school diplomas average 2.24 children.
Women with high school diplomas average 2.09 children.
Women with basic degrees have 1.78 children.
Women with advanced degrees have 1.88 children.
Women with financial stability are still having 16% fewer children than women lacking education.
