#3 results from a fundamental confusion people have that pay is based on people "deserving" something. Like it's an expression of virtue or your worth as a person or a reward for doing something good.
It's not. You're paid based on supply and demand and your negotiating skills, nothing more. It's not a golden star from your teacher that you're a nice boy. It's whatever you were able to convince the company the monetary value of your contribution is worth. That's all. Get over whether someone deserves this or that. I'll solve this once and for all: nobody deserves anything. You're responsible for figuring out how to provide value and capture it.
