The key difference between television programming before the 2000s was that the dad was the one the kids went to for advice. Sometimes the mother also, but the father was the rock with tons of wisdom. Leave it to Beaver, Ozzie & Harriet, Good Times, Little House, Cosby, etc. Since 2000, the dad is now the buffoon and the butt of all jokes. Mom or the kids are the smart ones.
Little House was designed as family entertainment. The books were designed for child/preteen entertainment. There are other books by Wilder for adults, but the books were really written for children. I read them in 4th -5th grade, I think. They would probably be interesting to many adults and an easy read, but they were written for a younger audience. They are great stories about western pioneer life. Buthering hogs, getting maple syrup from the trees, dealing with blizzards while feeding animals in a barn, death, Indians, wolves, the heartache and struggle that comes with farming (locust swarms, drying winds, and prairie fires, for example), and the joys of sitting around a fire, playing music, and dancing with neighbors. It's all great stuff, and I read them aloud to my kids, and recently gave my original books to my daughter to read to her children.
In the books, the family is not nearly as stable as in the TV series. They move A LOT. Pa is always looking for the next place to be successful. From an adult perspective, he is somewhat of a dreamer, and his family suffers as a result. Poor Caroline, she was a saint.
So I guess what I'm saying is, enjoy the books for what they are: a simple, innocent view of life during the pioneer era.
BTW, if you watch LHOTP Christmas Special and don't shed a tear, you aren't human, LOL.
