Pope Francis' political gambit

If you are a chess player, you will easily sense the political gambit of Pope Francis, when he attacked "money idolatry" and "trickle-down" theories on economics. Obviously, it is an attempt to capitalize on  greed or immorality in money. Admittedly, he maybe right on crude and naive trust being given to the goodness of those wielding economic power.

But does he possess a valid legal, moral and spiritual ground to attack them?

I don't think so, unless he attacks first the tradition of Roman Catholicism, which is much legally, morally and spiritually worst than anything on earth, in heaven and underneath the sea. 

He should attack first the "holy" cross, "holy" rosary, rosary beads and strings, and every Roman Catholic idol, which are being promoted by the alleged church.
