That's one point. I also just didn't see the need for him to state his hourly wage without giving any more details as if that set wage made all the difference. Afterall 21$/hour is nice but if your hours are let's say 20 a week, you'd make less than someone working 10$/hour having 50 hours a week. The missing information just seemed pointless for them to point out their hourly wage to begin with. Personal opinion of course on my behalf though.
