How we price our services depends upon how we view society and ourselves in that society.
If you believe in a communal state where everything is shared, than you'll share your services.
If you believe in a reward for your efforts, then you'll charge.
Do you believe in a hand out or a hand up?
I try to find some kind of work for the person who needs help. But I refuse to pity them, I think that's degrading.
I once sold a refrigerator, delivered, for $5. She came back later and wanted it for free.
Been there, done that, got burned!
