It's almost as if it's promoting a comforting but unrealistic narrative.

I find marketing such a strange idea.

I believe the Ancient Greeks hated these mind control techniques. But in modern society, we are told it's a good thing.

I'm not sure what is good about being tricked to buy average products at expensive prices. Samsung/Apple are my two examples in the tech world.

Yup, and it also fails to take into account inherent group interests. One example would be that homosexuals have an inherent group interest in having others accept homosexuality.

It isn't enough for an idea to be "more wise" or "more correct" or whatever for it go from a fringe idea to a mainstream one. Someone needs to have some reason to bother pushing the idea. Any idea with a dedicated group pushing it is more likely to go from the fringe to the mainstream.

Depending on how dedicated that group is, and what kind of resources they have to push the idea, there is no reason to believe that some idea being "more wise" or "more correct" is even necessary for it to go from the fringe to the mainstream.
