Capitalism's toddlerification of it's "successful" participants literally creates these meaningless dialogues. Our imbecilic hierarchies don't just extend to the economical, they affect these types of social norms heavily too. There will always be a cheap way to elicit prejudice over disadvantageous and unprofitable ideas especially if the voices are from "undesirable" individuals and groups, which depending on your brainwashing target can be literally anything. We have to be able to teach already brainwashed individuals critical thinking.
