I'd prefer humanity to evolve to understand greater complexity than set the bar low and leave it there. Should a language dumb itself down so it can be learned by more people? I'd argue that the cons outweigh the pros.
Indeed, not many people get very excited about kanji, but I think that's a failure in education, rather than a fault of the language that needs to be rectified. As an example, I think that Hangul is a brilliant phonetic script, but just because Chinese characters (Hanja, as they're called in Korea) are all but gone from most facets of Korean daily life, that doesn't negate the fact that almost 70 percent of the vocabulary comes from Chinese, and ignorance of those characters leads to all kinds of problems. In fact, it's lead to a vicious cycle of ignorance and wasted effort:
- The Korean education system requires students to intensely study almost as many Hanja as Japanese students>>
- Hanja have all but disappeared from common use>>
- Because of this, Korean students don't see any point in studying Hanja>>
- But neglecting Hanja hinders their understanding of their own language>>
- And so the Korean education system requires them to study hanja... and we're back to the top of this list.
The usefulness and importance of Hanja aren't impressed on young Koreans, so I have yet to meet one who actually LIKES studying it. The drill-to-death approach to education (and by education, I mean test-preparation) fails to inspire any passion or greater understanding in students, which means we have a whole lot of knowledge and not much wisdom floating around.
That's a greater issue than whether or not they use Hanja, but Korea is a great example of how eliminating Chinese characters from common use has succeeded only in increasing literacy rates, and has not actually lightened the workload on students. On the contrary, it has increased their burden AND removed the motivation of necessity from their education, ensuring their contempt of Chinese characters instead of interest therein.
