If you can't see how undercutting your so called colleagues undermines them then it would take longer than I have to explain it to you.
Tell you what. Why don't we just offer jobs on an auction basis? He/she who will work for the least (or better still pay the employer the most) gets the slot regardless of experience.
If someone is qualfied and capable of doing the job they should be paid accordingly. No haggling, no excuses and none of this nonsense about paying peanuts because the pilots are only doing it for the experience/it's a short contract/they owe their trainers money.
