But I can't help but wonder if these same cultural factors can go both ways and maybe we're obsessively focusing on just one effect. For example, it might be that deference to hierarchy and older people leads to children taking responsibility and care of their parents in old age more. It might even be that the elderly in these places live longer and more happier lives as a result and that this outweighs the (still tragic but rare) plane accident.
It reminds me a bit of the terrorism situation in the US. We obsess over these things which are relatively rare and spend great effort to eliminate. But what are we losing in the process?
