I remember that video being shown in my government class years back when I was in college. It was honestly terrifying at the time but now is pretty spot on. An Anime with somewhat of a similar concept would be Gachaman Crowds, it’s just not made apparent until the Director’s Cut OVA for season 1 and the second half of season 2.
It’s not as dark as the ending of this and there’s no masks. The villain causes this kind of cycle (find that out very early on) but it’s not shown till much later exactly how he operates.
