Maybe this was just the writing style at the time. 200 pages of storytelling, world building, details and plot development and then 20 pages to resolve and finish up. Frequently it doesn't even feel rushed, it is just less clear cut ending than newer books.
Most recent example I came across is Kramer vs Kramer. It's a short book overall, but the main plot is no more than 10% of the book and the resolution is two or three pages and then it just stops.
And sometimes it’s just affirming to read an author describe a character thinking the same thoughts one has or the same situation one finds oneself in.
I will also say that to me there is a massive difference between how much effort it takes to read one type of fiction versus another. I was reading Master and Margarita and I stopped because they simply kept introducing new characters and doing jumps for no reason. I'm sure I will get a bunch of well-read people telling me it's because I'm a poor reader or whatever, but I think that's bad writing.
