I think theres always been somewhat of a nostalgia for earlier/simpler times. Reading Waldon, by Thoreau he mentions similar things in the 1840s, as well as accumulating more "things" than one can realistically use in their lifetime.
Little House wasnt my thing, but I loved Gunsmoke and most of the other westerns in the mid-late 60s. I guess Ive always been more of an adventurist than farmer type person. I read tons of books about the Apache and Plains Indian Wars period, mountain men, anything to do with frontier and adventure was high on my list of interests, to the point I left the midwest, moved to Az, nomadded off and on several years off my motorcycle and truck, lived in a tipi a while, then upgraded to log cabins in the northern rockies. I even got running water after a while!
Ive recently found quite a few of the old TV shows online in various places. I havent had a tv in ages, but recently in sitting around in the midwest doing family estate and elderly parent stuff, Ive found some older western movies Id never seen before, Randolph Scott, Audie Murphy and others, as well as came to appreciate many of the old black and white Perry Mason episodes, and discovered Peter Gunn. All help to decompress and feel distanced from the pace and sensory overload that the modern world tends to heap on us.
Its interesting that we now can get hundreds of channels on TV, but some of the best programs are 40 or 50 or more years old.
