I’m so pissed off I’m about to quit

So first off I wanna say that I’m a baby tech, the hospital I work at is my first experience in this field, I started off with no prior experience and was hired last November 2022, I started at 14.50 and then eventually made my way to making 15.00 an hour. We just hired two new techs and today one of them approached me and was bragging about how he makes 16.50 an hour WITH NO PRIOR EXPERIENCE!!!!! I was obviously pissed off because I had to climb my way up from 14.50 to 15 AND HE MAKES MORE THEN ME AND IT IS HIS 3rd WEEK, I am seriously debating finding a new hospital to work at because we got hired under the exact same circumstances. I went to our office manager today and told her what he said to me and questioned why this was and all she said was “I get it” LIKE WTF, she proceeded to change the subject and ask me if the new tech as autism??? And then proceeded to tell me we need to tell eachother to stop playing on our phones in between appointments. SHE DIDN’T EVEN GIVE ME ANSWERS, the owner of the clinic is on vacation right now, but the day she gets back I’m going to talk to her about this (advice on how to approach this would be appreciated) and depending on how she reacts let’s me know if I need to find a new place to work because wtf. New guy is also a prick and pretending to know shit he doesn’t know and throwing HELLA attitude at the senior techs and questioning the doctors. AND SOMEHOW MAKES 16.50???? I’m livid
