Social Darwinism. The 'survival of the fittest' doesn't necessarily mean the survival of what's 'best.' Beetles might outlast humans, but they certainly aren't 'better' than the Da Vinci's or Beethovens, or even the tigers, of the world. So the premise of 'Social Darwinism' is flawed.
The socio-economic survival of the financial elites at the expense of the rest of us does not mean that they are 'best.'
