That hasn't been my experience, but the point is that if you can't convince someone to pay you more for similar work, then you're not underpaid. It's not about value, or how hard you work, or whatever. It's about how much money you can convince someone to pay you. That's the only thing that matters.

This is true, and which is why I have learnt you need at least two offers before switching jobs.
