After 12 years at my current airline, I have 28 days vacation. Excellent health care coverage and I get decent schedules. Plus my payrate is $95.42/hr.
Although I have to consider my options since we are unsure of the future, leaving will be difficult as the huge cut in pay, benefits and schedules would occur.
Some are at regionals because they're comfortable there. Some got stuck during the recession of 2008 and some just don't interview well. So don't pick on the lifers. Some are probably there no by choice.
