The simple facts that aviation is a very dynamic technology which constantly refines itself is overlooked by all the social speculators and chattering classes. They just don't want to face the truth that aviation has a small footprint instead they require a target one which unlike the rest is still disciplined, conformist, hard working and professional. Therefore aviation is readily accepted as the target to lock onto. Just like immigration certain industries are perceived through the fog of mystique and thus becomes an easy blame point. Ignorance of course fuels this further and there's plenty of that around society, in fact it's celebrated.
