English mogs the rest of the world in efficiency, aside admittedly from French (and the evolution of English grammar and syntax largely comes from there, plus half the vocabulary).
When people got tired of Latin the international and cultural language was French for 300/350 years, then switched to English mid 20th century due to US dominance.
The problem is that Americanos went too far in globalizing the language, with their stupid insistence on having foreign plebs speak the language. The French (and classical Latin beforehand) were more subtle by only using a global langage among elites so it wouldn't be dumbed down by this status.
