I also have absolutley no ambition to join the elite in the airlines. I'm quite happy in GA. The only problem is the money...........put quite bluntly, its crap. the climb to the higher echalons of the GA industry will be littered with crappy airplanes, crappy employers, and crappy people you will meet along the way, and when you get there, the rewards are hardly worth it.
But, in saying all that, if you enjoy a challange, have the ability to rise above the crap you will encounter along the way and love flying, you won't be alone in the career GA pilot race.
Admittedly, there are some jobs and companies that are far better than the average (RFDS is one of them) these, although not the highest paying positions, are the positions you should aim for.
Good luck, and I hope you get to have as much fun getting there as I did/am.
