What people seem to forget is history just repeats itself......Stagecoach drivers hated the introduction of the train and train companies hated the introduction of the Automobile who hated the introduction of the Airplane.
Industries change over time and either you hold on to what you have or change with it.....how big is the UK shipbuilding industry or the steel industry ?
It has however a huge impact on the people there and consequences and it would be foolish to ignore it.
Look at the way the development of IT has effectively wiped out travel agents and the next stage is the check in desk.
Going forward in the future its not inconcievable that Planes in the future no longer have Pilots onboard.
Laughable at this point in time BUT you program in every concievable eventuality and it is possible via computer.
Alternatively you have a Pilot or Pilots based in a centre who fly the plane and rely on onboard sensors to tell and show what is happening.
Not so laughable when you consider that currently Military personnel in Nevada are flying drone attacking people and equipment in Iraq and Afghanistan.
LCC's will just develop into something else over time but the Dinosaurs within Industrys just die, its reality of competition and it will occur again and again.
