I grew up poor(but no longer am). I can sympathize with some of the things she wrote, but not very many. I too talk to the janitor and cleaners. I once had a job like that.

What strikes me is that she describes a work-life that are quite a few years long, perhaps even decades, and she still is dirt poor apparently.

I know that no-one just gives money away, but how come she lives a frugal life and after years of working still is extremely poor?

Her writing makes me think she thinks like a beaten dog. Either she is exaggerating/lying or she has some other problems that are not actually money-related.
