I think the very same way when I read about, see or encounter such people. If not a literal “body snatcher”, a notorious soul- and intellect-snatcher has most definitely been hard at work in this country for a century, at least. Having made relatively quick work of tens of millions in the early years, he really put the shoulder to the wheel in the ‘60’s and ‘70’s. By now, he has clearly succeeded in putting most of the rest of us in real peril of having our minds and souls conquered in turn, like dominoes destined to fall absent intercession or intervention by a superior entity.
If not necessarily at the same level in terms of intellectual, political or cultural content, the remake of Invasion of the Body Snatchers” with Donald Sutherland is right up there with Orwell’s 1984 in terms of what U.S. citizens should be viewing/reading once they are old enough to contend with adult themes. IMHO 1984 probably shouldn’t be approached before age 16 for the reason stated, but Animal Farm by the same author should definitely be required reading by no later than eighth or ninth grade, if for no other reason than to get students prepared to read the real dystopian masterwork and understand and absorb the crucial lessons about humanity and its potentially fatal weaknesses that Orwell was trying to convey.
I also think of HG Wells The Time Machine with the beautiful, shallow, amoral, pleasure-seeking Eloi —and their dominant masters, the cannibalistic controllers the monstrous Morlocks —who provided everything to the Eloi so they lived in a utopia —and had no need to work or contribute. Problem is the Morlocks would routinely hypnotize them and harvest them for food.
Sci fi writers are the most prophetic again and again,
They have a keen sense of cause snd effect and the patterns of the human animal. Too bad we have amnesia when it comes to the perils of our history
