I suspect that if you dig deeper, the underlying cause of burnout being forced to spend a lot of effort over time and not being able to feel that you are living up to your values in return. You are running a marathon but never reach the finish line of the satisfaction of living according to your own moral code.
* That can come from overresponsibility if you have a value that says you should fix things that you see are broken.
* It can come from meaningless bullshit jobs if you have a value (which almost everyone does) that says your effort is meaningful.
* It can come from isolation if you have a value that it's important to be connected to others.
It can probably arise from any other value you might hold as long as you're forced to strive and yet can never reach it.
Honestly, I feel like values are deeply underconsidered in our current culture's thinking around psychology.
