Adam Smith said it

Here is an not often seen quote from Adam Smith that I'm not really sure what to make of,

"A half-starved Highland woman frequently bears more than twenty children, while a pampered fine lady is often incapable of bearing any, and is generally exhausted by two or three. Barrenness, so frequent among women of fashion, is very rare among those of inferior station. Luxury in the fair sex, while it enflames perhaps the passion for enjoyment, seems always to weaken, and frequently to destroy altogether, the powers of generation." --Adam Smith, An Inquiry into the Nature and Causes of the Wealth of Nations (1776)
