Haven't seen The Traitors, but recently started watching a Korean Netflix show called The 8 Show and the plot involves some mystery organizer (similar to Squid Game, I suppose) creating a setup that is a microcosmic version of trickle-down economics. I'm currently taking a break from the show because the behavior of the most powerful player in the game was so on point with what we see in reality, it became blood-boiling!
