Maybe so. But one truck accident kills far fewer people than one airline accident. So each individual pilot has considerably more responsibility than each individual truck driver.
Perhaps, but you could go back and forth on that all day. Look at the list of incidents involving at least 50 deaths on wikipedia[0], comparing aviation and road, there a difference, but it’s not an enormous difference.
My point is that I don’t think there’s a strong correlation between risk to public safety, and remuneration, nor between training and remuneration. There’ll likely be some correlation for both, but you can find huge variations in remuneration across different industries that can’t be explained by those factors.
Training? How long does it take to become a (professional) pilot? I bet it's longer than to get your chauffeur's license... but not so much longer to account for the pay difference.
It occurs to me, though, that vehicle cost might be a factor. How much does a new semi cost? $100,000, maybe? How about a new 737? $80,000,000. Does that influence pay?
