Translating the lectures or adding subtitles to them would help non-English speakers learn about economics. I am thinking of older persons in France, which often have never been exposed to sound economic thinking.
Hi there! Our Principles of Microeconomics course is available with French subtitles on YouTube: https://www.youtube.com/watch?v=g9uUIUqhrSQ&list=PL-uRhZ_p-BM4XnKSe3BJa23-XKJs_k4KY
We're working on adding French subtitles for other courses as well. :)
