True, but at the same salary? Probably not. In this field there's tons of stories where developers working on high profile franchises can't get work either if it's salary or location, etc. Resumes are also kind of useless in the gaming industry. It's more about who you know than what you know sadly. It's a plus to have a game credit under your belt but connections are almost infinitely more valuable.
But yes...generally he probably could have gotten grunt work anywhere at least.
At some point, people have to make decisions for themselves. I left a very good job with nice benefits because it consisted of repetitive movement that was placing strain on an old injury of mine. I was taking pain pills during every break and having trouble sleeping. I didn't blame the company, I simply decided that it wasn't the right job for me and left for the sake of my own well-being. I'm responsible for me. When it comes down to it, each person has to decide what they can and cannot handle. If he wants to stay at a job that's giving him nightmares for the sake of money then that's his own decision and one he's going to have to own.
