@Alchemist_Final @StillIRise1963 I heard the expression in the 1950s and 60s growing up in Los Angeles. I think people today are less likely to think of themselves as breeding stock or cattle as we've done for thousands of years. Children are no longer seen as assets but as expenses so families no longer aspire to have 8 or 10 kids "of good stock". It's no longer a point of great pride to say, "I have 37 grandchildren."
