I mean this in the nicest possible way (as a former Montrealer who also belongs to a minority ethnic group), but it would seem that the way you write English is discernibly non-native and therefore there was a trade-off in fluency that was incurred in your language acquisition. Unfortunately in North America, there is a subtle social price that is paid for lack of complete fluency in English (French in Quebec). Imperfect fluency is often perceived differently in different ethnic groups. If a Western European person (say a French or Italian person) makes mistakes in their English, it is exotic, but if an East Asian person makes mistakes, they are foreign. Things being what they are, it actually makes sense for certain minority groups to optimize for 100% fluency in English, and merely satisfactory fluency in other languages. I grappled with the same issues the OP did, and ultimately came to the same conclusion. It doesn't have to be 10x effort however, I agree with you there, but any effort needs to not be at the expense of proficiency in English. p.s. some Asian children tend to overoptimize and aim for better-than-the-average-native-speaker's fluency in English. Their investment generally pays off. Arthur Chu of Jeopardy fame talks about this.
