The question is: Why? Why would anyone do this to themselves and their society?
I suppose you want the practical reasons that make this system work today, and that is transforming whole countries into obedient tax farms so that the elites can implement their ideas of how the world should be (check Yuval Noah Harari for reference).
The "people" in the "music" video were put there to keep you in check in case you had different ideas about how your neighborhood should be and the things you can say in public.
As to the philosophical reasons...you can start by checking out Peter Turchin's "overproduction of elites". In a nutshell, technological progress makes it possible for the creation of larger and larger "lesser elites", that would have not been elites in the past. Before Gutenberg, a book cost as much as a house, because it had to be copied by hand. Today, you can read anything you want on a 100euro telephone. People that rose into the ranks of elites in the past had to have a range of skills, motivation and wisdom that made them extraordinary, since access to knowledge was so limited.
Today, you have armies of MBAs thinking they are the next Steve Jobs because they have a piece of paper with a stamp on it, armies of philosophy graduates thinking they are the next Platos.
When society fails to push them into the real elite (in their minds - they were never real elites) they gather in roving armies of desperados, attacking the status quo with the weapons of cultural Marxism, for two reasons: first, the existing (real) elites of the Left give them another piece of paper, one with "exemplar citizen" written on it, and second, they hope they will be given a piece of the pie after the current system goes down and another system is put in place.
They will not be given a piece of the pie - they will be executed or sent to labor camps (check out the story of the Soviet Union) but they are not smart enough to know that.
In the meantime, we get to endure these idiots who believe in COVID and Greenpeace preaching about their "original ideas" and (here in Europe) climbing the ranks of the European Union. Check out Nigel Farage speeches to those imbeciles when he was in the European Parliament.
