I always assumed the Purges were set up by a far right government to legally kill anyone who tried to organise against them.
Send goon squads (not the new ones) to smash up and kill coops, local farms, unions, uncooperative lawyers, journalists, etc.
Yes, folks can and do.
But Hollywood likes to good wash the current status quo, so let’s ignore PayPal’s union busting and censorship policies, bombing civilians, systemic racism, and take it up to 11 in a fictional future.
Or maybe I’m just jaded by the biggest fans of “purgey” settings being right wing folks.
