I really shouldn't have to say any of this but as someone who is in the process of learning a second language, I can tell that simple language makes things a lot clearer when you are not familiar with the language. Everyone on here started out reading simplified English while they were learning, including you native speakers. I'm sure no one here was reading on a college level in elementary school. It's seems very bigoted and hypocritical to call those trying to learn English dumb because they need it in a simplified version when you yourself would require the same simplicity if you were learning a language.
P.S. For those of you who say a simplified version isn't necessary because the watchtower is available in most languages need to consider the following. English is the most spoken language on earth, the watchtower isn't gaining(if not losing) any members in English speaking countries but has a lot of growth in countries where english is spoken as a second language. It makes sense to build the English skills of those in non-English countries so they can "witness" to the hundreds of millions of English speakers on earth. Simply put, English is a more valuable language then there native language.
