Where are we in the Psalms?

Psalms 9 and 10 arguably talk about the weak and poor suffering at the hands of the strong and rich.

Goldingay comments that "Most readers of this commentary therefore have to see themselves as the people who are being prayed against." (p184)

One can see where he gets this from, but to my mind it is absurd. What is fundamental to my identity? Not how rich or powerful I am, but whether or not I am humbly trusting in Yahweh. That this the basic dividing line in the Psalm and it tells you whether you can pray this prayer or cop it.
