I think this is a very important observation. Sometimes poverty doesn't look anything like this.

I'd like to note that although I grew up in "technical" poverty, e.g. in a small rural community with a median income of $11,121, very few saw much violence or any of the markers of poverty lifestyle this article talks about.

Although my anecdote is not scientific, I do think this has much more to do with observed culture than with an arbitrary signifier like poverty. Urban poverty and rural poverty are entirely different things, for instance. As is transient and temporary versus chronic poverty.
