Freaktrimmer,
I was a cadet not too long ago and although I agree with you that many cadets don't have passion for aviation, I don't feel its that big a deal.
Passion is not a prerequisite to being a good pilot. There are many people who are passionate about flying but cannot make the cut. There are just as many people who joined for the money but are very apt in their job.
What is important is to be professional and to keep learning. Passion is nice to have but not a "Need to have"
