And long may you remain unemployed my son!
I have been offered a full time position by the airline on the A320/321 before reaching 300 hours on type. I do not regret because the pay is great and I now have the job I wanted. Most of my friends are still instructors with 4 times my flight experience on a PA28 and their pay is 4 times less than mine.
I was not pleased to pay my line training, I had no choice. Once you start something and know your goal, you have to go to the end otherwise it's a waist of time, and time is money.
Yes working for free in order to get the experience is bad, but this is the situation nowdays, if you don't like it you're free to stay out of the game. I am just here to share my experience, it doesn't matter to me if you agree or not my decisions...
