I wonder how it compares when you also factor in benefits. I am pretty sure I don't make all that much on base pay, but hopefully my benefits make up for it a bit in that medical/dental/vision are covered, retirement pension match of 2:1 with me paying in 7% (so 21% of my pay each year), and a few other odds and ends that are likely more similar.
If someone making $10k+ more than me in a similar area has to pay out of pocket towards medical/dental/vision and doesn't get much retirement help, then it may balance out more. Otherwise I am likely just sticking around letting them pay me less than I deserve... We shall see what happens in under a year when I can actually register for my PE.
