Economic or Political Self-Interest or Selfishness

Key quote: "Is it really true that political self-interest, is nobler somehow than economic self-interest?" I think the venerable doctrine: "Total Depravity," gives us an answer to this question... 

A more nuanced (and accurate) understanding regarding how Capitalism works makes a clear distinction between "Self-Interest" vs. "Selfishness." On the whole, Economic Socialism assumes it has no "Self-Interest" and declares itself devoid of "Selfishness." Really?
