&gt; I followed several of the links the article was using to support the Social Darwinism claim. One only was actually making that claim (inc.com) and it was obvious pseudo-science, it has the wonderful line: &quot;Self-employment income is heritable&quot;.<p>Your post confuses me, because I think you&#x27;re lumping two <i>very</i> different -- almost contradictory -- claims together under the vague banner of &quot;Social Darwinism&quot;.<p>The inc.com article you are referring to suggests a <i>biological</i> mechanism (DNA molecules and genes), while this article refers to a purely <i>social</i> mechanism ($$$, influence of kin, learned behaviors.)
