Korean for literacy? When the English language has the most beautiful and meaningful written works of all mankind?
Literacy in terms of how many can read/write. Written Korean is very easy to learn (nigh unto trivial), having (unlike most languages) actually been created by an accomplished linguist (the then-king around 1500). With just 24 phonetic characters, plus a simple syllabatic representation, it’s actually much easier to learn to articulate written Korean than to comprehend it.
This in contrast with English, which has an insane number of linguistic exceptions, phonetic variations per given symbol, hominyms, etc. being a cobbling-together of multiple languages.
