Language isn’t just a means of communication, but it is the medium of propagating culture. That’s why culturally Canada is similar to the USA while Mexico (and the rest of Latin America) to Spain. One huge advantage the USA has over Europe is that practically everyone speaks a single language. A Californian can fly 6 hours to New York City, and feel just at home, with the same language and thus, a similar culture.

One huge advantage of the European Union over India is the same Latin writing script everywhere except in Bulgaria and Greece.

When a non-Spanish speaker sees a panaderia in Spain, he might not know what he means. When he walks into it a few times, he associates “panaderia” with a bakery. That’s not true for a Tamilian in Varanasi, he sees “भोजनालय” and even though he might be able to guess “bhojan -> food” and “aalaya -> house”, the Devanagari symbols are a bit too far apart from the Tamilian script to decipher. This is even though both the scripts are of the same alphasyllabary type (having a character/व्यंजन and a character modifier/मात्रा), a writing system unique to Indosphere.
