Simply saying that Esperanto is easier than English or French is not enough. Just the other day, I heard an item on the BBC World Service. The announcer was introducing someone who was going to speak about a new constructed language, called Glosa. In his introduction the announcer mentioned Esperanto and other attempts to create an international language, which he said had failed because they were too difficult. It's true, however, that the grammar of Esperanto is an absolute nightmare for most Asians.
Many Asian languages have a much simpler grammatical structure than Esperanto.
Language reform projects are by no means uncommon in relation to living languages. However, most of these occur in the third world, which is perhaps why most Esperantists are unaware of them and assume that a living language can only change by evolution. However, there is nothing to be done about it now for the simple reason that Esperantists will never accept changes which go against the Fundamento. Although Esperanto will never be an easy language for non-Europeans, it could become significantly easier for them than it is at the moment. One of the major reasons why Esperanto is difficult is because of its excessively large vocabulary of root words.
