I have no optimism on this, but I’m thinking of the post-WWII Baby Boomer generation and how they were raised.
To be clear: I’m not a fan of Dr. Spock’s specific methods of child raising.
However, what interests me is the notion of a widespread cultural switch in how “everyone” decided that children should be raised in accordance with this new book. A whole generation brought up with a fairly common approach to parenting.
Could that happen again? Probably not. But just imagine a genuinely good book, emphasizing traditional values, practical values, discipline, and manners. A new generation brought up generally better than the last few.
But I don’t think out fractured society could possibly pull that off.
I recommend GENERATION OF PSYCOPATHS, where the author blames Dr. Spock as part of the reason Boomers turned out the way they did.
