Point 1. There are people who live off the backs of others by being paid to do a job that produces no wealth, like bean counters, bank / office workers etc. Then you have the people who create the dosh to pay for the aforemetioned like factory workers, pilots,engineers, etc. Unfotunatley the former almost always dictate terms to the latter.
Point 2. If you take even a small commuter turboprop and fill it with 50 punters , half of them "suits", you have probably got about £100 million in collective liabillity every time you get airborne, if you take into account the hull ,high net worth individuals, etc so the guys and gals at the sharp end are between them being paid £55 - 60 k a year to manage that liabillity , on a daily basis sometimes up to 6 sectors a day in all weathers. I wonder what other profession whould put up with being so grossly under paid.
