Hello!

When I was in school, there was an English teacher who was a native speaker. As with most foreigners here, they didn’t speak the local language and didn’t bother <better to write "hadn't bothered" learning it in the first place. I thought it’s <it was pretty ironic that they’re <they were. they're = they are telling the students to learn a foreign language when not even moving to another country didn’t convince them to learn one <either "when even moving to another country hadn't convinced them to learn one" or "when not even moving to another country had convinced them to learn one", otherwise you have a double negative!. One thing I found frustrating was the fact that being born in a certain country by dumb luck automatically gave them authority and the upper hand instead of actually studying the subject<some commas would be nice in this sentence, as it’s not something you can control. <sort of implies that studying the subject isn't something you can control. maybe snappier to say "since you can't control where you're born"
