And who do you reckon will be in charge of making things right during the flight when things badly go wrong?!
Having been in different faces of aviation I can tell you that piloting is overall one of the easier jobs.
Most of the time a pilot just gets to push and pull buttons and switches, seated in an airconditionned aircraft, getting served coffee by an F/A.
Compare that to working on an understaffed tarmac, exposed to the weather elements, noisy engines and APU' s every single day, having little to no time to take a seat or a sip of coffee because you are under time pressure of delayed flights.
It doesn' t mean that piloting is a simple job. Sometimes you face situations like you mention.
But day to day and overall it is less tough, "easier" in that sense.
Let' s face it, if you like airplanes and you want to work on them, why does it have to be as a pilot? To most the answer to themselves will be that it is the most pink-glassed/rosy/glamourous option.
Been there, done that.
My point being that there is no one job better than the other, but if you really have a passion for aviation and that you can' t become a pilot within reasonable conditions, there are other challenges to be met within the same industry.
So why take the risk of going broke to absolutely become a pilot if you have other options within the industry that will actually pay you to work (but are tougher) and let you manage flight operational matters while being able to enjoy a ride in the cockpit from time to time?
