I just want to discuss ONE point.
Number of children.
Even in old, black & white "classic" movies, I'm shocked at how children are portrayed.
In "It's a Wonderful Life", the main characters have a whopping 4 children. In 1946.
In these older movies, children are portrayed as some kind of rare trophy, a rare treasure, a tribute to years of love. Because you might only have one or two of them.
Yes, each child is a unique treasure; a gift from God. But if you only watched black & white movies, you'd swear it takes 2 or more years of married love to have each child!
I understand that not EVERYONE can have a dozen children, for various reasons. But the protagonist of "It's a Wonderful Life" and his wife married young, and were in good health. All things being equal, children tend to come in greater numbers than what they ended up with. Especially if you follow the 1950's customs of letting baby "cry it out" and bottle feeding!
(24-hour nursing -- exclusive breastfeeding -- causes delayed return of fertility)
You know how divorce was portrayed in movies as "everyday normal" BEFORE actual real-world divorces breached the "5% of marriages end this way" mark?
We all know what happened: the real world soon followed. People started imitating what they saw on TV.
