Social Darwinism and Social Evolutionism

From the appropriation of Darwinism by Capitalism, i. e. the interpretation of 'survival of the fittest' as 'survival of the wealthiest', it follows that a thief with a gun is superior to their victim.  But any further implication that 'fitter' is equivalent to 'more highly evolved' exposes a fundamental confusion in Darwinism itself--between the Survival principle and the Evolutionist principle.  Illustrating that confusion is the widely-held hypothesis that a cockroach could survive a nuclear holocaust, though few would conclude that a cockroach is, therefore, more highly evolved, i. e. more complex, than a human.  For that reason, Social Darwinism is not equivalent to Social Evolutionism, which leaves the concept of Evolutionist Economics unsettled.  Instead, the fundamental principle of that concept must promote the Evolution of the Species, not the Survival of the Individual.  Now, as has been previously discussed, the human thumb illustrates that the process of Evolving consists in an increase in Complexity, or, equivalently, in Versatility. Thus, Collective Versatility is an example of a fundamental principle of Evolutionist Economics.
