The document discusses the significant economic impact of the 'language gap' faced by immigrants in the U.S., particularly regarding their limited English proficiency which restricts their job opportunities and career advancement. The current ESL programs are inadequate, with long waiting lists and inconsistent quality, leaving many immigrants unable to attain the necessary language skills to compete in the job market. Addressing this issue could lead to substantial economic benefits for immigrants and the communities that rely on their labor, as improving language skills could increase their earning potential substantially.
