It’s not hyperbole, this is an actual serious issue in America. The overwhelming majority of Americans do not have high enough reading skills to extrapolate and cross reference data from things like text books and journal articles. Something like 40% of American adults can’t read well enough to comprehend multi-step prompts (e.g. they struggle with stuff like bus schedules). About 15-20% of American adults can’t read at a basic level, very simple things like medicine bottles. Depending on the survey these numbers can vary a bit

Part of this statistic is because we have a high immigrant population that doesn’t speak English as their primary language but the main reason is that we’ve simply eroded education quality for decades. I work with teenagers who are in high school and can barely throw together a coherent email. Statistically, most adults don’t read for pleasure at all.
