I always tell people who ask me what I did with my PhD: I managed to get a good education and become a trusted professional despite the schooling system.
The only thing my degree did for me was prove to my first employer that I was willing to sit tight for years and go through the pointless motion of getting a degree. I managed to grind through to the end to get an idiotic piece of paper, and that told him I was unlikely to flake out on him after 3 months on the job. That's all my degree was ever useful for.
