There are lots of ways to more accurately describe, whether with statistics or with prose, the state of the world. But that would go against the interests of the ruling capitalist class in portraying capitalism as, at the very least, the least worst option.

I would say it has to do with the Marxist understanding of cultural hegemony. The ruling class determines, based on their class interests, the cultural norms, such as the way we typically frame facts and figures. It doesn't hurt that media and academia is controlled by the ruling class and used to reproduce the ideology.
