Exactly! I'm currently going through this process. I'm just pointing out that "quit your job" is not always an option. Regardless of how burnt out I am, I'm still gonna show up to work tomorrow and do as much as I fucking can to do valuable things for the company. No I know this is a shitty way to waste away my life and 20s but I honestly don't know any better way to live.
They should spend years 6 and 7 looking for better prospects, and move to greener pastures as soon as they possibly can.
I personally immigrated to a new country and was locked in for 4 years at a job that demanded more and more of my time and life energy. Leaving was one of the most long-term positive things I've ever done, and the 4 years was worth it.
Again, it's going to take years, and be hard work. And it's going to be worth it.
