Psalm 146

The psalm writer gives God the credit for insuring justice is served and the hungry are fed. God is responsible for freedom of those imprisoned, sight resatored for the blind, and honoring the down trodden. God keeps watch over the wanderer, window, and orphan. But there is no mention of God's plans for the wealthy, self-confident, or politically connected. Is it because everyone in the latter group is also in the former group?
