Critical Response paper

What is Social Darwinism (explain in your own words, without using outside sources) and what role does Social Darwinism play in Charles Dickens’s A Christmas Carol? Granted, Charles Darwin published his Origin of Species in 1859, a few years after Charles Dickens published A Christmas Carol in 1843, but to what extent is an early form of Social Darwinism at stake in A Christmas Carol? Please write a critical response based on this question.
