Sorry but the reason the hourly cost is not used by the unions in public discourse, is because hardly anyone else earns that sort of money. That information would only further entrench the 'silvertail' perception of pilots.
As a five year trained university graduate with two degrees, which I completed while working full time, I earn $95 an hour working both for myself and as a contractor to the Government on occasion. My services are in demand and I can't accommodate everyone I would like to, but even so that is the going rate.
