The Pope and Selfishness

In a My Way article, Frances D'emilio reported that Pope Benedict XVI said in his Christmas message,

"Wherever an increasingly uncertain future is regarded with apprehension, even in affluent nations...In each of these places may the light of Christmas shine forth and encourage all people to do their part in a spirit of authentic solidarity...If people look only to their own interests, our world will certainly fall apart."

The Pope has an obligation to speak on moral issues. I dispute the economic order that may be implied in, or insinuated into his statement by others.

I assume that "a spirit of authentic solidarity" refers to generous behavior towards others as taught by Christ. Let's now assume that we double our authentic solidarity by cutting selfishness in half. How would this alter economic institutions?

I would guess that little would change in the market oriented Western world, and that poor nations would institute economic reforms that would make them more like us.
