You did everything right. You got the degree, took the entry-level job, and waited for the promotion that never came. Or maybe you skipped the degree entirely, and now you're watching less-capable colleagues with better credentials pass you by. The advice you've been given—'go back to school,' 'build your personal brand,' 'just apply to more jobs'—treats the symptom, not the disease. The disease is that the economy no longer pays for what you know. It pays for what you can prove you can do, right now, with verifiable evidence.
