So, we agree on the definition of integrity. However, i don't see how it may be applied in this scenario. I fail to see what integrity has to do with whether a pilot over 60 chooses to stay in aviation or not. Fortunately I am not 60, yet. However, one day I will be, and hope to see out my career until 65.
I started flying later in life and am no way near ready to retire, mentally or financially, none of which is due to 'poor' decisions. Your arrogance in assuming that al pilots of a certain age that are not financially secure have made bad decisions is astounding as well as borderline discriminatory.
What other metrics could we apply to the pilot work force to reduce pilot numbers?
