GP here. You and @maginary make an interesting point, namely that standardized spelling helps non-native speakers. The problem with English is that much of our existing standardized spelling is quite non-intuitive to pronounce, e.g., rough, through, thorough. Perhaps some kind of spelling reform as discussed by @philipps and @jherdman below would help, although other comments here also discuss the problems that have arisen with such efforts.
