> You know how many people in the US are illiterate? 21% [2] Do you think that number will increase or decrease if we got rid of compulsory education?
Just 20% in 1875[1], despite the primitive education system of the time. Is the answer no change, it being limited by the innate capabilities of the people, not limited by what they do?
The source above yours and the one on Wikipedia are using different metrics for literacy. These are generally not comparable. Measuring literacy in a useful way, especially over historic timescales, is harder than it sounds.
