How do i deal with someone getting what they dont deserve?

at my camp, which i absolutely LOVE, i applied to be staff this summer. they said that they were only taking 5–6 applicants, but in the end they took 14 new staff. 6 of them dont deserve to be on that list, in mine and other peoples opinions. how do i deal with my jealousy for this job? and btw, this camp is my life. home is the place where i live when im not at camp.
