Airlines are popular employers specifically because they offer a clear vision of future pay increases and better, more prestigious, schedules. People, especially pilots, are willing to put up with a lot early on because they are confident that sticking with the plan will eventually allow them to earn double and triple their early-career salaries.

Same thing happens in law, investment banking, etc... the hardest workers are often the youngest and least-paid. They do it because they know big money may come later.
