“Researchers found that increasing the linguistic similarity between two languages by 10% increased their trade by 5%. It’s not the only benefit. Speaking a language makes you more likely to work at, migrate to, and invest in countries and companies of that language. If you speak Hungarian, you have nowhere to go or invest besides Hungary. But if you learn English, the world is your oyster.”
