It's priming. You have to present very obvious scams, to then conflate the concept of being scammed with political ideology... which doesn't necessarily follow.

Propaganda is really interesting in the way it carries a narrative. It's like a good movie, gives you an idea about what you're going to watch, and then slowly flows to the places you expected it to go to, but it does it in unique and interesting way.

There is certainly something innate in the human mind that loves these predictive narratives.
