Run a business IN your own, native language FOR people who also natively speak that language.
That can be done if ESL students in foreign colleges and universities are allowed to write their papers in their own native language. Are you planning to suggest this to the governments?
Or are you now suggesting that an ESL writer can not even target ESL customers? Leave the ESL customers for ESL writers, because ET anyway does not have writers who write ESL, or does it?
