Alphabet is such an underrated invention. It's probably higher in significance compared to the invention of wheel. It's the original "bicycle of the mind". For example, Korea pivoting from Chinese characters to its own alphabet or Hangul is very well documented including the positive effects it has in the much improved Korean literacy and civilization after the conversion. Fun facts anyone can learn Hangul alphabet in a single day if they wanted to but the same cannot be said to Chinese characters. If your mother tongue is Korean (e.g Korean American) that only just started learning, it only take one day turnover from illiterate to literate.
Scripts being the main driver of literacy is a pet peeve of mine. It's not the script, it's the schooling system. The high rates of literacy in modern states are just a result of the school system - Japan has a high literacy rate, for example, and their writing system is either the worst in the world or close to it.
That said, the characters are a whole boatload of unnecessary extra effort, and as a student of the two languages, the artificial illiteracy created by kanji, where I often just can't read words I've known for years, is simply maddening. Not having to wrestle with characters does free up a lot of time for both native and foreign students alike.

Yes, it's probably the worst since even Microsoft until now still struggle to provide proper search solution for Japanese names in their Windows OS due to their multitude of writing systems.
By sheer wills of course you can make everything hard feasible but that does not means it's efficient and effective. I consider Japanese as a unique country with extraordinary people that can collectively overcome adversity, that's include a non intuitive and difficult writing systems.

Heritage speakers (of any language, not just Korean) often have limited vocabulary and limited exposure to complex grammar. Being able to sound out words wouldn't be enough to allow a heritage speaker able to fluently read a newspaper.
How many Korean-Americans know the Korean words for things like 'legislature', 'inflation', or 'geopolitical tensions'?
