&quot;ie are there reasons to not act in a selfish manner 100% of the time.&quot;<p>Certainly, but the feeling I get from the original comment is: &quot;There are <i>no</i> reasons to act selfishly <i>ever</i>.&quot;  I&#x27;m not arguing in favor of 100% selfishness; I&#x27;m arguing against a zero-tolerance policy towards it.<p>Further, the <i>form</i> of the whole thing is troubling.  If someone asked you, &quot;How should we help the impoverished citizens of X?&quot;  My first response would likely be foreign aid of some sort, or perhaps free trade.  But I don&#x27;t get the feeling that proponents of open borders would be satisfied with those (assuming for the sake of argument that they would indeed help).  Beggars can&#x27;t be choosers; the focus on <i>one</i> method makes it feel more like a shakedown than a plea for help.
