It's a matter of perspective, eh?
For people who really hate their job, it's hard to understand that other people love their job enough to want to keep working. Love their job? Impossible. It has to be the money.
Wish I was able to do what your friend is doing. Then again, I love my job, so I'd keep doing it even if I didn't have to. Well, maybe not quite as much of it. ;)
Yet, they argue that they are empathetic...
The "not quite as much of it" resonates with me. I would like to do some other things on the side, or my job on the side :)
