Just remembered I have an adult friend who also delivered papers. She was paid the same abysmally low rate, but found it worth it for these reasons:
She is the most financially strategic and frugal person I know, so every dollar is valuable to her.
She finds it gets her exercising (she does 3x/week).
She liked knowing her neighbourhood and neighbours, and found this enhanced that connection.
It's one of the rare jobs she can do with her kid (with disabilities) alongside.
When I talked with the person from another country about delivering, she was shocked at the low pay. I explained that it's considered a kid job, paying for a fancy popsicle or -after some weeks- perhaps movie tickets. She said in her country it was considered a serious career -with responsibility akin to carrying mail, such that only adults would be given it...and be paid according to adult needs.
