> [Formal education in software development] certainly put me in a great position upon graduating college and got me a great job, but nothing increased my skills more than simply working with more experienced developers in a full-time role.

That's, fine, but that's not what we're talking about. We're talking about management placing an (implicit, unrecognized and uncompensated) expectation on one developer on a team who happens to have a lot more experience than their peers. In other words, management is happy treating him as equal to his peers when providing compensation, yet expects significantly more output for the same pay.
