If you think that's a modern problem, you haven't paid attention.
It wasn't the Milennials that made the cold war strike against the American heartland with that masterpiece of communist propaganda called the Smurfs. S.M.U.R.F.: Socialist Men United under a Red Father. Take one look at Papa Smurf's red(ha!)-clad ass and try to not see Karl Marx. No names, just descriptions of their overspecializations. A classic case of "to each according to his abilities." Entrepreneur Smurf was probably starving in a gulag somewhere. And Gargamel is one of the more belligerent straw capitalists ever placed in fiction.
On the flip side of that coin, there's G.I. Joe. A perfume-scented love letter with nudes enclosed to the American Military-Industrial complex. Red and blue lasers to coddle the moral majority, and every week a new gadget to pitch to procurement. A desperate attempt to pull the military out of the drug-addled mess it had been throughout the 70's. I'd be amazed if there wasn't a lost episode where Duke and Hawk took executives from General Dynamics and Lock-mart to a titty bar.
Millenials weren't making those.
Meanwhile, today, My Little Pony has given masterclasses in "dealing with bitches in your life without becoming a bitch yourself." The She-Ra reboot is a deep as fuck exploration in divided loyalties, trusting but verifying, and doing the wrong thing for the right reasons. And the Ducktales reboot is openly using Scrooge vs. Glomgold to point out that not only is ethical capitalism possible, it's fucking ideal!
Just preach and indoctrinate, my hairy ass.
