No, I agree with you, I don't think money is the solution here. But to my understanding, if, for example, someone is going to teach a course to mechanics, vehicle technicians, or weapons technicians, and they are unilingual, as a qualified instructor--they have the necessary experience, they've taken the necessary training courses, but they're unilingual--it's a challenge for them to actually offer bilingual training. To me, finding someone who is qualified as well as bilingual is where the challenge is.
But from the comments that you just now made, are you stating that actually most instructors are bilingual and they're just choosing to speak one language?
