Aliens: “Marx was right”
Me: “Yeah”
Aliens: “Well enjoy your doomed planet”
Me: “Cool thanks”
“Can’t you like save us with your technology or something”
“Against the rules sorry”
This is literally a plot point of Strugatsky (of Stalker fame) novel (and movie) Hard to Be God. Communist Earth finds a planet of human-like aliens stuck in medieval ages but decides to help only by influencing the politics with spies and shit, because going ham would be “robbing people of their history”.
