Maybe we'll start listening to him

Probably not, but one can hope. From Pope Benedict XVI's latest encyclical, "Caritas in Veritate":

"Striving to meet the deepest moral needs of the person also has important and beneficial repercussions at the level of economics. The economy needs ethics in order to function correctly - not any ethics whatsoever, but an ethics which is people-centered...

Much in fact depends on the underlying system of morality. On this subject the Church's social doctrine can make a specific contribution, since it is based on man's creation "in the image of God" (Gen 1:27), a datum which gives rise to the inviolable dignity of the human person and the transcendent value of natural moral norms. When business ethics prescinds from these two pillars, it inevitably risks losing its distinctive nature and it falls prey to forms of exploitation; more specifically, it risks becoming subservient to existing economic and financial systems rather than correcting their dysfunctional aspects."

Whether you're Protestant or Catholic, Pope Benedict XVI's encyclicals are always worth reading if you can spare the time.
