For a change we could try to see the problem from ‘their’ perspective. Is there anything within their culture that could be used to improve safety – how can flying a GA be presented as something of honour, to be sought, to be rewarded?
In the context of this subject of culture and flight safety I recommend you read a parallel series of postings on the Australian Pprune forum under the main subject heading of "Real Men Don't Go Around." In particular a post by username Ozgrade3 discusses his experiences with culture and which refers to flight training schools in Australia that specialise in training overseas students. His assessment is that you will never change the cultural influence in some countries - it doesn't matter how much you try as an instructor. Many will agree with his point of view. Been there-done that.
