At one point do you get punched in the nose enough times to realize you aren't meant to be a boxer? These people clearly didn't make it in academia. As much as I want to be an NFL quarterback, sometimes you have to accept reality and try for a different goal.
Well, what if you wanted to be an NFL quarterback, had all the skills, but couldn't find a job because Joe Montana, Dan Marino, John Elway etc.--greats in their day--had tenure?
You can post on Twitter about how unfair it is, but I would rather take control of my own destiny and do something else. Living in my car outside the football stadium in the hope that someday I'll be hired would be naive. The same for the adjuncts.
