First, in your breakdown, there is literally no space for unoaid volunteer work wich is topic of the thread.

Second, working job is about earning money not about helping others.

Regardless of why you do it, working an honest job does help others. Money is the reward you get for that behavior.

My point is if you explicitly choose to work for free you're opting out of that reward structure. It seems odd to do that and then turn around and complain that "the world where we are living in" isn't rewarding you for your work.
