I don’t think it’s an impossible task to get students quality language instruction that gets them on track to proficiency in a given foreign language. It’s doable, and people manage to do so all the time. The issue is more that people often don’t see the benefits of it in their daily lives where English suffices for everything, and they most certainly don’t see enough of a benefit that they wouldn’t collectively lose their shit over a proposed property tax hike intended to adequately fund foreign language instruction in the local school district. They’ll gladly fork over a few million dollars in tax money to trick out the football field, but to hire enough new teachers to have kids start learning French in 3rd grade and continue until graduation? Not a chance in hell. Ditto for French-language media purchases for the school library, or any other auxiliary purchases that would facilitate a genuine attempt at teaching and learning a foreign language.
