What is a commonly believed fact, that is actually untrue?

That's because neoliberal economics are not designed to work in the favor of most economic participants(nonruling classes) in the first place.

It's designed for capital accumulation and growth, and when wealth continues to grow in one small part of the population, it declines for the majority. If though, enough wealth is extracted from the lower classes to the point where they can't consume enough anymore, that's when the economy is no longer going to be beneficial for the top. Unless labor is completely automated by then. This is why social and economic safety nets exist along with a minimum wage.

So, to put it frankly, it is known by influential investors (along with critics of neoliberalism of course) what benefits the economy. They aren't going to make it obvious or freely available (even in acadamia), because that would literally be counterproductive to their continuous economic benefit.

Citigroup made a few internal memos and economic assessments a few years ago essentially backing up what I'm saying but they've gone to great lengths to suppress it's publicity. You can Google citigroup plutonomy memos to read them yourself if interested.
