Another advantage of making Korean easier to learn (read anyway) than Japanese (by a good margin) and Chinese (by gigantic margin) was when they started writing/reading from left to right and across the page instead of down in columns. (granted you can still find the old styles around).
But the Chicoms haven't the authority to give English-speakers lectures on using Pinyin orthography when writing in the Queen's English. Or even Fulton Fish Market English.
