Didn't know our neighbours produced so much coke, kudos to them I suppose.
This has been reported for decades, especially publicized when they kicked out US drug enforcement groups to favor coca plantation owners (in order to protect their traditions with the plant.) Meanwhile, Bolivia's cocaine exports have risen for years.

Everyone learns from their efforts, as well: getting other-culture aspects "correct" for different perspectives is tough and an attempt was made. The movie Moana took years of research and collaborative work with local cultural representatives who contributed greatly to its symbols, images, characters, etc. and it *still* pissed off some people who said they knew better.
I think RomanHume went over the top in reply and don't appreciate all points that were attempted, but you should look at your responses, as well. I usually don't go for "both sides do it," but in this case the shoe seems to fit.
