question:  What is the main reason that Gubelin is so resentful of Si’s decision?
context: They also had a banquet for him, complete with speeches by such bigwigs of the Department of Space Exploration as Academician Lofting Gubelin and Doctor Hans Girard-Perregaux. In fact, Academician Gubelin was possibly the only living man on North America who still wore spectacles. His explanation was that a phobia against having his eyes touched prohibited either surgery to remould his eyeballs and cure his myopia, or contact lenses. Doctor Girard-Perregaux was convinced Gubelin would have even worn facial hair, had he but a touch more courage. Slumped in an autochair in the escape room of his Floridian home, Lofting Gubelin scowled at his friend. He said, "Nevertheless, both you and I conform with the present generation in finding it far more pleasant to follow one's way of life in the comfort of one's home than to be confronted with the unpleasantness of facing nature's dangers in more adventurous pastimes." Gubelin, half angry at his friend's argument, leaned forward to snap rebuttal, but the other was wagging a finger at him negatively. He is now legally eligible for retirement. He was drafted into the working force reserves, served his time, and is now free from toil for the balance of his life. Girard-Perregaux was wagging his finger again, a gesture that, seemingly mild though it was, had an astonishing ability to break off the conversation of one who debated with the easy-seeming, quiet spoken man. Man has always paid lip service to adventure, hardships and excitement, but in actuality his instincts, like those of any other animal, lead him to the least dangerous path. If it is admitted that our organization has degenerated to the point that we haven't a single pilot, then it might well be that the Economic Planning Board, and especially those cloddies on Appropriations, will terminate the whole Department of Space Exploration." Girard-Perregaux said gently. Girard-Perregaux nodded his agreement.
output:  He fears the end of the Space Exploration program, and for mankind’s research of space to come to an end.
options:  He doesn’t want to have to go through the effort of training a new spaceman, as it’s very costly and time consuming.  He regrets not having the opportunity of space exploration himself.  He fears the end of the Space Exploration program, and for mankind’s research of space to come to an end.  He hates the Welfare State and how it’s taken away people’s drive to learn and explore.
