Let me guess you walked straight into a well paying BA and didn't have to find a job, didn't you
I bet if you was in a newly graduated pilots position you'd grab anything you could. Anyone would, the salaries for an FO are low, but the captains isn't that bad in the grand scheme of things, plus time to command will be lower its a low cost buget airline what do you expect? If you dont like it dont apply, it won't stop others who want to land that all important first job.
