So the question might be reversed, should everyone with the same job description be paid exactly the same, regardless of work output or experience?
This is a good question. All people inflate their own sense of worth. Workers who claim to work 80 hours a week are often making very different choices about how to manage their time as someone who claims to work 40. It's one half of the Dunning-Kruger effect (the other half being that people of high capability often underestimate the difficulty of what they do).
Now I'm not saying that you're exaggerating the amount of work you did in comparison to others (especially those tricksy women, amirite?), but it would be consistent with what we know about human nature and the actual data from the workplace of people who claim to work long hours. Studies have shown that the more hours people claim to work over 55, the more they're exaggerating how many hours they actually work. People who claim to work 75-80 hours a week are usually overestimating by at least 20 hours.
Competence is a complicated thing masquerading as a simple thing. No, people who have the same job title as you shouldn't necessarily make the same amount of money. Your pay is based on performance reviews, training, proven competence and a whole slew of other inputs. The problem is, a lot of those so-called metrics have a built-in bias. And in a salaried workforce, those biases can really run rampant. That's why in countries with healthier, more dynamic economies, you will see pay based on seemingly arbitrary measures like job title and seniority. This was an innovation of the labor movement and led to the most productive workforces in the world.
I have no doubt that you're a competent, hard-working guy. That's my built-in bias because I like you, Ol Olsoc. A lot of times, we find agreement around here. We have things in common. If I were overseeing a performance review of you, I'd probably be predisposed to rate you highly. I'd certainly be predisposed to rate you more highly than the woman who's been a bitch to me every since I made that joke about the one-eared elephant at Miller's retirement party.
Now, get the picture?
