What a strange hill to die on. English is the colonial language, and its global success was singularly due to imperialist hegemony. This is taught at the university system level and is in every textbook on the subject. I love a good myth about capitalism just as much as the next exploited worker, but attributing the success of English to trade is equivalent to teaching children myths about Thanksgiving and Washington chopping down a cherry tree.
English is widely spoken because it was the colonial language enforced at the highest levels of society. This is still true today and is currently a primary plank in the political platform of US conservatives.
There are libraries of books written solely on this subject. Your bizarre hypothesis ignores this and instead points to slavery and trade. More to the point, there are new articles on how English was enforced on subjugated people published on an almost weekly basis. Last week, the article I read on this topic was about how indigenous orphans were prohibited from using their native language and forced to use only English. But let’s talk about glowing myths about trade and slavery instead which have literally nothing to do with it.
"During the period of colonization…Maori were banned from speaking their native language in public places including schools, and forced to speak the foreign language of English…Maori were deprived…of their language, but also of the dimensions of culture and history inherent in language customers and worldview."
Why do you think an irreversible binomial employed as a thought-terminating cliché in the form of an argumentum ergo decedo is an appropriate response?
