Years of experience in the industry is a poor indicator for how much somebody can actually accomplish. What matters is how many of those moments were focused, and is the stuff you're learning useful for the future.

And if you're 3 or 4 times more productive and useful than another employee in your field, no company will ever pay you 3 or 4x what that other employee makes. The only way out of a company not valuing you accurately is starting your own company.
