I’ve been thinking of the MAGA movement using this framework (though I hadn’t seen this great little essay before). A lot of its adherents are older people who have retired and have a lot of free time. Many of them grew up in an age of going to concerts and other mass events, (though I don’t think Woodstock actually changed the world). Many of the events can be “joined” in a slightly less passive way than merely watching TV, but are similar in that a set of professionals produce it and then you basically attend or watch.
Also it is participatory, and is not just older people, so people can jump in and use the same sense of spectacle to be seen as well. Q is a good example, but there are many.
Another is the anti vaxer movement which arose at a time when people were not financially desperate but had a lot of free time.
Regardless of what you think of these phenomena, one cannot deny that they have “changed the world in the interim”.
I used to be an unalloyed fan (and was trying to work towards) of a future of universal unemployment: a utopian future where robots do all the work, the marginal cost of manufacturing is nil, and humans just do what they like: write bad poetry, hang out, etc. I never anticipated that such a Star Trek world free of wants would still have political movements.
