The ideal ruler

Is well described in Psalm 72:

May he defend the afflicted among the people
and save the children of the needy;
may he crush the oppressor...
For he will deliver the needy who cry out,
the afflicted who have no one to help.
He will take pity on the weak and the needy
and save the needy from death.
He will rescue them from oppression and violence,
for precious is their blood in his sight... Psalm 72 (TNIV)

Hmmm...I fail to see anywhere in there that (s)he will line their own pockets—or the pockets of the ones who backed him/her!. Obviously an oversight on the part of God, isn't it!

Or, maybe not:

Has not God chosen those who are poor in the eyes of the world to be rich in faith and to inherit the kingdom he promised those who love him? But you have dishonored the poor. Is it not the rich who are exploiting you? Are they not the ones who are dragging you into court? Are they not the ones who are blaspheming the noble name of him to whom you belong?—James 2 (TNIV)

Then why are the rich held up as so blessed by God? I fail to see it in scripture...I must be missing something—for which I can't help but praise God!
