I am not sure I understand you Desert185. You seem to be in agreement with the statement that people who like flying should be considered selfish if they want to continue as long as they can. You then say that the guilty party is someone else. Are the authorities the guilty party (as you put it)? Or is someone else to blame and of what? Life is not always fair and I can accept that people envy or even resent others they perceive as getting a better crack of the whip.
Life expectancy and people's potential useful working life has increased. The skills required by an airline pilot have also changed. Not everything has got better. But flying a modern jet is definitely easier than flying used to be on earlier generations of aircraft. Conversely pilots have had to become more efficient, with longer working hours for less pay. There are also many more of us than there used to be with quite different life experiences from earlier generations. I am pretty sure I will not continue to 65. But I certainly do not think that those who do are selfish.
