Return,
You say you chose flying because of your love of it, you knew that it was an expensive, yet highly paid, business before you entered into it.
You carry on to say that you do not believe there is another profession that exists where you must pay a very very large amount of money just to get into a position were you can apply for a job, well you knew that it was expensive before you ventured into it and do you think that a taxi, bus or truck driver is going to be in a position to apply for those jobs without the appropriate training.
The aviation industry owes you nothing, you entered into it because of your love of it in preference to less expensive trained positions as already mentioned, so what if you had wanted to be a F1 racing driver or an astronaut, are those industries meant to fall over backwards for you just because of your love for it?
