What is not equal about having one official language in which government and business is done? What is fair about ballots or other government documents being done in English and Spanish but not accommodating more than 7000 other languages in the world?Not equal access.
Having everybody learn English and having one official language in a country in which 80+% of the citizens speak English is a huge incentive for new immigrants or existing citizens to learn the language. Those who don't know the language need to bring an interpreter along unless the government office or the business happens to have somebody who speaks their language.
