 Many people have commented that this is also a useful tool for actual immigrants, as Esperanto speakers are normally much friendlier and more willing to see the immigrant as a "human" compared to the normal natives of the country.For example, it's suggested that an English speaker in Japan should make friends with Esperanto speakers instead, because the Esperanto speakers won't "simply use the friendship as a way to get free English lessons".Esperanto was originally a language that one had to learn entirely through books, and even today most people live apart from each other and converse through the internet, so writing and reading are a big part of Esperanto culture.
