another way to look at it is: just because you're excellent in one role, does not mean there's an upgrade path at any given business to improve salary+expectations.

Some businesses structure this intentionally, to avoid the upward progression of salaries, and other businesses just arnt churning through projects and clients quick enough to expand to fit the upward momentum of their talent.

Recognizing the real constraints on your value to a business model is important to not get stuck in the backwash of business value.
