Barbara Ehrenreich wrote an excellent book, "Nickel and Dimed," on how exhausting and precarious the lives of poor (= minimum wage-earning) people are, based on her experience trying to live off minimum wage.

In my life, I have been dirt-poor (homeless) and pretty well-off ($200k/yr), and my experience agrees with her reporting. Financial predators seek out the poor because 1) there are lots of them; 2) they don't have a lot of effective defenses; and 3) society, and poor people themselves, tend to blame the poor for their poverty (as the parent comment mentions).

I have a running dad-joke with my kids that "I'm not smart enough to be poor." The truth is, I'm not hard-working enough either. Being poor sucks. The poor know it. Many of them are as smart and hard-working as the statistical "us" are. I wouldn't be surprised if there's a correlation between financial literacy and revolutionary attitudes about changes to the economic status quo.
