What is "welfare racism" and do you agree or disagree with the underlying thesis that the U.S. welfare system is deliberately "racist"? 

In your answer, make sure to define racism and welfare racism and provide at least three examples with evidence in support of your thesis. The answer should be approximately 2 pages long, well written, and make references to either the course readings or external sources (reputable internet resources count), which ought to be referenced at the end of the document. I recommend you prepare your answers outside in a Word document and then copy and paste the answer into the Answer field below.
